ANALYSIS OF SPECTROPHOTOMETRIC AND PHOTOM ETRIC DATA FOR PRIMARY SPECTROPHOTOMETRIC STANDARDS

Spectrophotometric catalog of 238 bright stars was compared with the d ata of the Tian Shan photometric catalog in the WBVR system and system atic errors were found in the published energy distributions in the sp ectra of primary standards of the Moscow and Alma-Ata spectrophotometr ic catalogs - beta Ari, gamma Ori, beta Tau, alpha Leo, eta UMa, alpha Lyr, alpha Aql and alpha Peg, as well as the WBVR system standard sta rs HD 221525 and HD 5015. These errors are very likely to be caused, a mong other factors, by the error in the energy distribution of the Veg a spectrum derived by Hayes. The analysis of the photometry of these t en stars in four photometric systems allowed us to obtain new, correct ed energy distributions in their spectra, which substantially improved the agreement between the observed and synthetic magnitudes.
