Spectrophotometric Standards
Listed in IVOA Registry (Virtual Observatory)
The catalog contains energy distribution data of 82 stars of 7-8mag belonging to spectral types A0-G2.
Description
Spectral energy distribution is presented in the range 3400-7500{AA} with 50{AA} step. The observations were made in the period 1991-1996 by means of the spectrophotometer working at the regime of the photon counting.
Scanner was installed at the 60-cm Zeiss reflector of the Sternberg Institute Crimean Station. Eight early type stars were used as spectrophotometic standards: {beta} Ari, {gamma} Ori, {beta} Tau, {alpha} Leo, {eta} UMa, {alpha} Lyr, {alpha} Aql and {alpha} Peg. The accuracy of the monochromatic fluxes is about 2% in the ultraviolet, 1% in the visual range an 1.5-2% for {lambda}>7000{AA}.

The energy distribution data are expressed in erg/(cm^2^.s.cm)*10^-6^.
