Table information for 'specphot_stand_cat.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource 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.
