vo@fai.kzspectroscopystars One-dimensional reduced optical stellar spectra obtained at the Three College Observatory (TCO) with the eShel spectrograph on the 0.81-m telescope. This collection includes the full supplied archive, including the stars in the separately published hot-supergiant subset and additional stellar targets. Wavelengths are computed from the original linear IRAF WCS in Angstroms and served in meters. Fluxes are relative; continuum normalization is recorded only where supplied in the metadata. Resolving power R=12000 is adopted from the existing collection documentation, not measured separately for each spectrum.https://dachs.fai.kz/tco_echelle_spectra/q/ssa/infoArchiveResearchIsServedByFAI archives ObscoreFAI archives TAP servicehttps://dachs.fai.kz/tco_echelle_spectra/q/ssa/ssap.xml?GETapplication/x-votable+xmlPOSICRS position of target objectdegcharSIZESize of the region of interest around POSdegrealBANDWavelength (range) of interest (or symbolic bandpass names)mcharTIMEMidpoint of exposure (MJD)time.epochcharFORMATMIME type of the file servedmeta.code.mimecharAPERTUREAngular diameter of aperturedegphys.angSize;instr.fovcharSNRSignal-to-noise ratio estimated for this datasetstat.snrcharREDSHIFTRedshift of target objectsrc.redshiftcharTARGETNAMECommon name of object observed.meta.id;srccharTARGETCLASSObject class (star, QSO,...; use Simbad object classification http://simbad.u-strasbg.fr/simbad/sim-display?data=otypes if at all possible)src.classcharMTIMEDate last published.charFLUXCALIBType of flux calibration (ABSOLUTE, CALIBRATED, RELATIVE, NORMALIZED, or UNCALIBRATED).charSPATRESSpatial resolution of datadegpos.angResolutioncharWAVECALIBType of wavelength calibrationmeta.code.qualcharCOLLECTIONA short handle naming the collection this spectrum belongs to.charSPECRPLower limit to spectral resolution power (λ/Δλ) as a single number.realPUBDIDDataset identifier assigned by the publishermeta.ref.ivoidcharCREATORDIDDataset identifier assigned by the creatormeta.idcharWILDTARGETShell pattern of target observed (case insensitive)charWILDTARGETCASEShell pattern of target observed (case sensitive)charREQUESTThis is queryData for the default operation; some services support getData as wellcharTOPOnly return the TOP "best" records (on this service, this usually is equivalent to MAXREC, so no ranking is implied).integerCOMPRESSReturn compressed results?charRUNIDAn identifier for a certain run.
