Spectrophotometric Standard Stars Catalog
Listed in IVOA Registry (Virtual Observatory)
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):**
Description
- 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**.
