Atmospheric Composition by Solar Absorption (177 to 1216 A)

NSSDCA ID: 1975-092A-03

Mission Name: D2B
Principal Investigator:Mr. P. Cruvelier


This experiment measured the stellar UV radiation in the antisolar direction with a low spectral resolution (about 400 A) between 792 and 3075 A. The sensitivity of the instrument allowed detection of BO type stars down to 8th magnitude. In addition, a UBV photometer measured the radiation from the stars and the sky background.
