ANALYSIS AND CORRECTION OF THE SPECTRAL E NERGY-DISTRIBUTIONS OF 238 SECONDARY SPECTROPHOTOMETRIC STANDARDS

Formulas permitting the determination of corrections to the spectral e nergy distributions of standard stars based on the comparison of spect rophotometric and photometric data are presented. The spectral energy curves for the spectrophotometric standards beta Ari, gamma Ori, beta Tau, alpha Lee, eta UMa, alpha Lyr, alpha Aql, and alpha Peg are refin ed using data from the Almaty spectrophotometric catalog and the magni tudes in different bands in the WBVR, UBVR, uvby, Vilnius, and Arizona 13-color photometric systems. The results obtained are compared with those of other authors. The spectral energy distributions for stars in the ''Catalog of 238 Secondary Spectrophotometric Standards'' are cor rected, taking account of new data for the standards, and reduced to t he Tyan' Shan' photometric catalog system. This reduction noticeably d ecreased the disagreement between the synthesized and observed magnitu des in various photometric bands.
