Scientific paper

The homogeneity of the spectrophotometric catalog comprising 867 stars observed at the Shternberg Astronomical Institute Crimean station (spectral energy distributions published separately) is tested by comparison against the Johnson-Mitchell (1975) 13-color photometry for stars tied to each of eight standards, both in the E76 system on which the catalog is based and in the E81 system, which utilizes subsequent Shternberg observations. Conversion from E76 to E81 diminishes the mean deviations of the spectrophotometry from the 13-color photometry throughout the 3200-7600 A range for all the standards except Gamma Ori. In E76 the standards Alpha Aql and Alpha Leo show the largest deviations (for wavelengths about 5000-6000 A).
