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.
