J/AZh/72/80    Primary Spectrophotometric Standards     (Mironov+, 1995)

Analysis of Spectrophotometric and Photometric Data for Primary Spectrophotometric Standards Mironov A.V., Moshkalev V.G. <Astron. Zh. 72, 80 (1995)> =1995AZh....72...80M
ADC_Keywords: Spectrophotometry Description: A spectrophotometric catalog of 238 bright stars was compared with the Tyan Shan photometric catalog in the WBVR system. An analysis of the photometry of ten stars in four photometric systems led to new, corrected energy distributions in their spectra, which substantially improved the agreement between the observed and synthetic magnitudes.
