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 3400-7500Å with 50Å 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: β Ari, γ Ori, β Tau, α Leo, η UMa, α Lyr, α Aql and α Peg. The accuracy of the monochromatic fluxes is about 2% in the ultraviolet, 1% in the visual range an 1.5-2% for λ>7000Å. The energy distribution data are expressed in erg/(cm2.s.cm)*10-6. File Summary:
