Beginning of ReadMe : III/209 Spectrophotometric Standards (Biryukov+ 1998) ================================================================================ Spectrophotometric Standards of 7-8 mag Biryukov V.V., Borisov G.V., Glushneva I.N., Shenavrin V.I. <Astron. Astrophys. Transact., 16, No1 (1998)> Spectrophotometric Standards of 7-8 mag. Supplement I. Biryukov V.V., Borisov G.V., Glushneva I.N., Shenavrin V.I. <Astron. Astrophys. Transact., (in press)> ================================================================================ ADC_Keywords: Spectrophotometry ; Energy distributions ; Stars, standard Keywords: energy distribution - photometry - standards Abstract: The catalog contains energy distribution data of 82 stars of 7-8mag belonging to spectral types A0-G2. Spectral energy distribution is presented in the range 3400-7500AA with 50AA 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>7000AA. The energy distribution data are expressed in erg/(cm^2^.s.cm)*10^-6^.
