Abstract

The results of brightness observations of the Sun as a star by DIFOS experiment onboard CORONAS satellite are presented. The observations are performed in six spectral channels, namely 350, 500, 650, 850, 1,100, and 1,500 nm. The description of DIFOS multichannel photometer is provided. Data processing was done by analytic signal transformation. The theory of analytic signal transformation is presented.
