The Table Access
Protocol (TAP) lets you execute queries against our database tables,
inspect various metadata, and upload your own data. It is thus the
VO's premier way to access public data holdings.

Tables exposed through this endpoint include: main from the asteroids_obs_tab schema, main from the fai_agn schema, main from the gcvs_gaia_tess schema, main from the geomagnetic_field schema, main from the grb_photometry schema, obscore from the ivoa schema, main from the maksutov_50_telescope schema, main from the mesa_bin_6_4_002 schema, main from the neutrons schema, main from the pn_spec_res_table schema, main from the pulsars schema, alt_identifier, authorities, capability, g_num_stat, interface, intf_param, registries, relationship, res_date, res_detail, res_role, res_schema, res_subject, res_table, resource, stc_spatial, stc_spectral, stc_temporal, subject_uat, table_column, tap_table, validation from the rr schema, main from the schmidt_telescope_lc schema, main from the solar_flux schema, main from the specphot_stand_cat schema, data from the spectra_agn_archive schema, data from the spectra_pn_archive schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, main from the wr_wc_wo_sequence schema, main from the wr_wn_sequence schema.</description><referenceURL>https://dachs.fai.kz/__system__/tap/run/info</referenceURL><relationship><relationshipType>IsServiceFor</relationshipType><relatedResource ivo-id="ivo://fai.kz/__system__/obscore/ObsCore">FAI archives Obscore Table</relatedResource><relatedResource ivo-id="ivo://fai.kz/rr/q/create">GAVO RegTAP Service</relatedResource></relationship></content><capability standardID="ivo://ivoa.net/std/TAP" xsi:type="tr:TableAccess"><interface role="std" version="1.1" xsi:type="vs:ParamHTTP"><accessURL use="full">https://dachs.fai.kz/tap</accessURL></interface><dataModel ivo-id="ivo://ivoa.net/std/obscore#core-1.1">Obscore-1.1</dataModel><dataModel ivo-id="ivo://ivoa.net/std/regtap#1.2">Registry 1.2</dataModel><language><name>ADQL</name><version ivo-id="ivo://ivoa.net/std/ADQL#v2.0">2.0</version><version ivo-id="ivo://ivoa.net/std/ADQL#v2.1">2.1</version><description>The Astronomical Data Query Language is the standard IVOA dialect of SQL; it contains a very general SELECT statement as well as some extensions for spherical geometry and higher mathematics.</description><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-udf"><feature><form>gavo_getauthority(ivoid TEXT) -&gt; TEXT</form><description>returns the authority part of an ivoid (or, more generally a URI).
So, ivo://org.gavo.dc/foo/bar#baz becomes org.gavo.dc.

The behaviour for anything that's not a full URI is undefined.</description></feature><feature><form>gavo_ipix(long REAL, lat REAL) -&gt; BIGINT</form><description>gavo_ipix returns the q3c ipix for a long/lat pair (it simply wraps
the 13c_ang2ipix function).

This is probably only relevant when you play tricks with indices or
PPMXL ids.</description></feature><feature><form>gavo_match(pattern TEXT, string TEXT) -&gt; INTEGER</form><description>gavo_match returns 1 if the POSIX regular expression pattern
matches anything in string, 0 otherwise.</description></feature><feature><form>gavo_mocintersect(moc1 MOC, moc2 MOC) -&gt; MOC</form><description>returns the intersection of two MOCs.</description></feature><feature><form>gavo_mocunion(moc1 MOC, moc2 MOC) -&gt; MOC</form><description>returns the union of two MOCs.</description></feature><feature><form>gavo_specconv(expr DOUBLE PRECISION, dest_unit TEXT) -&gt; DOUBLE PRECISION</form><description>returns the spectral value expr converted to dest_unit.

expr has to be in either energy, wavelength, or frequency, and dest_unit
must be a VOUnit giving another spectral unit (e.g., MHz, keV, nm, or
Angstrom). This is intended to let users express spectral constraints
in their preferred unit independently of the choice of unit in the
database.  Examples::

	gavo_specconv(obscore.em_min, "keV") &gt; 300
	gavo_specconv(obscore.em_max, "MHz") &gt; 30
	gavo_specconv(spectral_start, "Angstrom") &gt; 4000

There is a variant of gavo_specconv accepting expr's unit in a third
argument.</description></feature><feature><form>gavo_specconv(expr NUMERIC, expr_unit TEXT, dest_unit TEXT) -&gt; NUMERIC</form><description>returns expr assumed to be in expr_unit expressed in dest_unit.

		This is a variant of the two-argument gavo_specconv for when
		the unit of expr is not known to the ADQL translator, either because
		it because it is a literal or because it does not look like
		a spectral unit.  Examples::

			gavo_specconv(656, 'nm', 'J') BETWEEN spectral_start AND spectral_end
			gavo_specconv(arccos(phi)*incidence, 'Hz', 'eV')
		
		Clearly, overriding known units is likely to yield bad results;
		the translator therefore warns if an existing unit is overridden
		with a different unit.</description></feature><feature><form>gavo_vocmatch(vocname TEXT, term TEXT, matchagainst TEXT) -&gt; INTEGER</form><description>returns 1 if matchagainst is term or narrower in the IVOA vocabulary
vocname, 0 otherwise.

This is intended for semantic querying.  For instance,
gavo_vocmatch('datalink/core', 'calibration', semantics) would be 1
if semantics is any of calibration, bias, dark, or flat.

For RDF-flavoured vocabularies (strict trees), term will expand to the
entire branch rooted in term.  For SKOS-flavoured vocabularies (where
narrower is not transitive), only directly narrower terms will be included.

Both the term and the vocabulary name must be string literals (i.e.,
constants).  matchagainst can be any string-valued expression.</description></feature><feature><form>ivo_geom_transform(from_sys TEXT, to_sys TEXT, geo GEOMETRY) -&gt; GEOMETRY</form><description>The function transforms ADQL geometries between various reference systems.
geo can be a POINT, a CIRCLE, or a POLYGON, and the function will return a
geometry of the same type.  In the current implementation, from_sys and
to_sys must be literal strings (i.e., they cannot be computed through
expressions or be taken from database columns).

All transforms are just simple rotations, which is only a rough
approximation to the actual relationships between reference systems
(in particular between FK4 and ICRS-based ones).  Note that, in particular,
the epoch is not changed (i.e., no proper motions are applied).

We currently support the following reference frames: ICRS, FK5 (which
is treated as ICRS), FK4 (for B1950. without epoch-dependent corrections),
GALACTIC.  Reference frame names are case-sensitive.</description></feature><feature><form>ivo_hashlist_has(hashlist TEXT, item TEXT) -&gt; INTEGER</form><description>The function takes two strings; the first is a list of words not
containing the hash sign (#), concatenated by hash signs, the second is
a word not containing the hash sign.  It returns 1 if, compared
case-insensitively, the second argument is in the list of words coded in
the first argument.  The behaviour in case the the second
argument contains a hash sign is unspecified.</description></feature><feature><form>ivo_hasword(haystack TEXT, needle TEXT) -&gt; INTEGER</form><description>gavo_hasword returns 1 if needle shows up in haystack, 0 otherwise.  This
is for "google-like"-searches in text-like fields.  In word, you can
actually employ a fairly complex query language; see
https://www.postgresql.org/docs/current/textsearch.html
for details.</description></feature><feature><form>ivo_healpix_center(hpxOrder INTEGER, hpxIndex BIGINT) -&gt; POINT</form><description>returns a POINT corresponding to the center of the healpix with
the given index at the given order.</description></feature><feature><form>ivo_healpix_index(order INTEGER, ra DOUBLE PRECISION, dec DOUBLE PRECISION) -&gt; BIGINT</form><description>Returns the index of the (nest) healpix with order containing the
spherical point (ra, dec).

An alternative, 2-argument form

ivo_healpix_index(order INTEGER, p POINT) -&gt; BIGINT

is also available.</description></feature><feature><form>ivo_histogram(val REAL, lower REAL, upper REAL, nbins INTEGER) -&gt; INTEGER[]</form><description>The aggregate function returns a histogram of val with nbins+2 elements.
Assuming 0-based arrays, result[0] contains the number of underflows (i.e.,
val&lt;lower), result[nbins+1] the number of overflows.  Elements 1..nbins
are the counts in nbins bins of width (upper-lower)/nbins.  Clients
will have to convert back to physical units using some external
communication, there currently is no (meta-) data as lower and upper in
the TAP response.</description></feature><feature><form>ivo_interval_has(val NUMERIC, iv INTERVAL) -&gt; INTEGER</form><description>The function returns 1 if the interval iv contains val, 0 otherwise.
The lower limit is always included in iv, behaviour on the upper
limit is column-specific.</description></feature><feature><form>ivo_interval_overlaps(l1 NUMERIC, h1 NUMERIC, l2 NUMERIC, h2 NUMERIC) -&gt; INTEGER</form><description>The function returns 1 if the interval [l1...h1] overlaps with
the interval [l2...h2].  For the purposes of this function,
the case l1=h2 or l2=h1 is treated as overlap.  The function
returns 0 for non-overlapping intervals.</description></feature><feature><form>ivo_nocasematch(value TEXT, pattern TEXT) -&gt; INTEGER</form><description>ivo_nocasematch returns 1 if pattern matches value, 0 otherwise.
pattern is defined as for the SQL LIKE operator, but the
match is performed case-insensitively.  This function in effect
provides a surrogate for the ILIKE SQL operator that is missing from
ADQL.

On this site, this is actually implemented using python's and SQL's
LOWER, so for everything except ASCII, your mileage will vary.</description></feature><feature><form>ivo_normal_random(mu REAL, sigma REAL) -&gt; REAL</form><description>The function returns a random number drawn from a normal distribution
with mean mu and width sigma.

Implementation note: Right now, the Gaussian is approximated by
summing up and scaling ten calls to random.  This, hence, is not
very precise or fast.  It might work for some use cases, and we
will provide a better implementation if this proves inadequate.</description></feature><feature><form>ivo_simbadpoint(identifier TEXT) -&gt; POINT</form><description>gavo_simbadpoint queries simbad for an identifier and returns the
corresponding point.  Note that identifier can only be a literal,
i.e., as simple string rather than a column name. This is because
our database cannot query simbad, and we probably wouldn't want
to fire off millions of simbad queries anyway; use simbad's own
TAP service for this kind of application.</description></feature><feature><form>ivo_string_agg(expression TEXT, delimiter TEXT) -&gt; TEXT</form><description>An aggregate function returning all values of
expression within a GROUP contcatenated with delimiter</description></feature><feature><form>ivo_to_jd(d TIMESTAMP) -&gt; DOUBLE PRECISION</form><description>The function converts a postgres timestamp to julian date.
This is naive; no corrections for timezones, let alone time
scales or the like are done; you can thus not expect this to be
good to second-precision unless you are careful in the construction
of the timestamp.</description></feature><feature><form>ivo_to_mjd(d TIMESTAMP) -&gt; DOUBLE PRECISION</form><description>The function converts a postgres timestamp to modified julian date.
This is naive; no corrections for timezones, let alone time
scales or the like are done; you can thus not expect this to be
good to second-precision unless you are careful in the construction
of the timestamp.</description></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adqlgeo"><feature><form>BOX</form></feature><feature><form>POINT</form></feature><feature><form>CIRCLE</form></feature><feature><form>POLYGON</form></feature><feature><form>REGION</form></feature><feature><form>CENTROID</form></feature><feature><form>COORD1</form></feature><feature><form>COORD2</form></feature><feature><form>DISTANCE</form></feature><feature><form>CONTAINS</form></feature><feature><form>INTERSECTS</form></feature><feature><form>AREA</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-conditional"><feature><form>COALESCE</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-string"><feature><form>LOWER</form></feature><feature><form>ILIKE</form></feature><feature><form>UPPER</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-offset"><feature><form>OFFSET</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-type"><feature><form>CAST</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-unit"><feature><form>IN_UNIT</form></feature></languageFeatures><languageFeatures type="ivo://ivoa.net/std/TAPRegExt#features-adql-common-table"><feature><form>WITH</form></feature></languageFeatures><languageFeatures type="ivo://org.gavo.dc/std/exts#extra-adql-keywords"><feature><form>TABLESAMPLE</form><description>Written after a table reference, TABLESAMPLE(10) will make the database only use 10% of the rows; these are `somewhat random' in that the system will use random blocks.

The data service includes:

* **Observables**: Three components of the geomagnetic field vector (X, Y, Z) and the total field amplitude (F), measured in nanoteslas (nT).

* **Data Resolution**:

	- XYZ components measured at a 1-second frequency.

	- F component measured at a 5-second frequency.

	- Derived minute averages for XYZF components available in real time.

	- Absolute measurements performed two to three times per week.

The service provides open access to minute- and hour-resolution data
(XYZF components and the geomagnetic K-index) from 2003 onward via
the Institute of Ionosphere’s website (https://ionos.kz/).
Minute-resolution variation data since 2004 are also available through
the INTERMAGNET network. Data prior to 2003 are available upon request.

The dataset is maintained by the Institute of Ionosphere and is
additionally accessible through the Kazakhstan Space Weather Portal
(https://ssa.fai.kz/, registration required), which also offers
interactive plots and visualizations.</description><table><name>geomagnetic_field.main</name><description>

Grid of Close-Binary Evolution Models

This dataset contains a grid of close-binary evolution models computed with the 
**MESA** (Modules for Experiments in Stellar Astrophysics) code, version `r24.08.1`. 
The primary objective is to investigate the dependence of binary interaction on 
the initial orbital period.

**Model Configuration:**

* **Donor Star (M1):** Fixed initial mass of 6.0 M_sun. The evolution is 
	followed self-consistently.
* **Companion (M2):** Represented as a point mass of 4.0 M_sun.
* **Orbit:** Initially circular; the grid is constructed by varying the initial 
	orbital period.

**Physics and Assumptions:**

* **Mass Transfer:** Implemented via the *Ritter prescription* for Roche-lobe 
	overflow (RLOF).
* **Efficiency:** Fully conservative mass transfer is assumed.
* **Angular Momentum:** Includes losses due to gravitational radiation, 
	magnetic braking, and systemic mass loss.
* **Tides:** Tidal synchronization of the donor star is accounted for.
* **Exclusions:** Wind mass transfer and irradiation effects are not included.

**Termination Criteria:**

Calculations are terminated if:

1. Roche-lobe overflow occurs at the very first timestep.
2. The system undergoes overflow through the outer Lagrangian point (L2).

The setup is designed to isolate the role of the initial orbital period in 
determining the onset of mass transfer and the subsequent evolutionary regime.</description><table><name>mesa_bin_6_4_002.main</name><description>

This resource provides a compiled dataset of Galactic planetary nebulae
derived from absolute optical spectroscopy and supplemented by selected
values from the literature. Based on these data, fundamental physical
parameters were calculated, including sizes, densities, electron
temperatures, and central star characteristics.

The table includes:

* Object identifiers, excitation classes, and interstellar extinction at Hβ.

* Morphological and distance properties: angular diameters (Diam_arcsec), linear sizes (Diam_pc), and heliocentric distances (D_kpc).

* Electron densities from [SII] 6717/6731 ratios.

* Effective temperatures of central stars estimated both by the Zanstra method (T_HI) and empirical [OIII]-based calibrations (T0_[OIII], T1_[OIII]), given in units of 10**4 K.

* Timescales: duration of available observations (delta_t_obs_year) and model reproduction intervals (delta_t_model_year), linked to evolutionary models by Bertolami (2016, A&amp;A 588, A25).

* Absolute emission-line fluxes for Hβ, HeII 4685, [OIII] 5007, Hα, [NII] 6583, HeI 6678, [SII] 6717/6731, HeI 7065, [ArIII] 7136, and [OI] 7324, with measurement uncertainties and (where relevant) a power-of-ten exponent.

Each measurement is provided in a machine-readable format, separating values,
uncertainties, and exponents into dedicated columns. This ensures precise
numerical handling and interoperability with Virtual Observatory services
and pipelines.</description><table><name>pn_spec_res_table.main</name><description>

The “Orbita” Radio Polygon at an altitude of 2750 meters 
conducts solar radio emission observations using 
state-of-the-art equipment. This includes instruments for 
monitoring solar radio flux at frequencies of 1 GHz and 2.8 GHz,
as well as the Callisto solar radio spectrograph, which is part 
of the international e-Callisto network. These tools enable the 
detection of solar radio bursts of types II, III, IV, and V, and 
provide valuable insights for forecasting the geo-effectiveness 
of solar flare activity.

The provided dataset consists of daily tables, where each table 
corresponds to a single observation day. The data includes two columns:

- **Obs_time**: The time of observation at the detector (UTC).
- **Flux [SFU]**: The solar flux unit measurement, representing the intensity of solar radio emission in SFU (Solar Flux Units).

The data are collected and provided by the Institute of Ionosphere,
(https://ionos.kz/) and are also available through the Kazakhstan
Space Weather Portal (https://ssa.fai.kz/, registration required),
which additionally offers interactive visualizations and graphs.</description><table><name>solar_flux.main</name><description>

The **Spectrophotometric Catalogue of Stars** (A.V. Kharitonov, V.M. Tereshenko, L.N. Knyazeva, 2011) provides calibrated monochromatic irradiances for bright northern-hemisphere stars and is intended for absolute/relative flux calibration of spectra and photometry.

**Content (one row per star):**

* Identifiers: sequential catalogue number, common name (if any), **BS** and **HD** numbers.

* Astrometry: J2000.0 right ascension and declination (also given in decimal degrees as *raj2000*, *dej2000*).

* Photometry and classification: visual magnitude **V**, colour index **B−V**, spectral type, trigonometric parallax (when available).

* Notes/flags: *st_ds* (short classification/remarks), *n* (mantissa exponent; see below).

* Spectrophotometry: monochromatic irradiances **F_λ** at fixed wavelengths from **3225 Å to 7575 Å** in **50 Å** steps (columns *f3225*, *f3275*, …, *f7575*). Values are given as **mantissae**; the full physical value is

	*F_λ = mantissa × 10^{-6}* in units of **W·m⁻²·m⁻¹**.

**Intended use:**

* Absolute/relative flux calibration of long-slit and fiber spectra.

* Cross-checks of instrumental response and atmospheric extinction curves.

* Educational and research tasks in stellar astrophysics.

**Coverage:**

* Wavelength grid: 3225–7575 Å, Δλ = 50 Å, continuous per star.

* Typical targets: bright standards of spectral classes **O–M**, luminosity classes **I–V**.</description><table><name>specphot_stand_cat.main</name><description>

This catalogue contains results of **photometric and spectral observations** 
of seven Galactic **Wolf–Rayet stars** of the **WC and WO sequences**, 
obtained in 2021–2022 at the *Fesenkov Astrophysical Institute (FAI), Kazakhstan*.

The observing programme included moderately bright stars (mostly fainter than *V = 10m*) 
observed in **B**, **V**, and **Rc** photometric filters, 
as well as **medium-resolution spectra** for measuring absolute fluxes 
in prominent emission lines.

For each object, the table provides:
	* identifiers (WR catalogue number, alternative name),
	* spectral subtype,
	* equatorial coordinates (J2000),
	* literature photometry (B_cat, V_cat) and reference codes,
	* date of observation and Julian Date (JD−2400000),
	* measured **B**, **V**, **Rc** magnitudes with their errors,
	* and absolute fluxes and equivalent widths for a set of emission lines, including  
		**C III λ4650**, **He II λ4686**, **C IV λ5017**, **He II λ5411**,  
		**He II + C IV λ6560**, **C III λ6744**, **C IV λ7065**, and **C II λ7234**.

These data were **first published** in the paper
