Stern, R. ; Bowyer, S. Abstract The paper reports results of the most extensive survey to date of the EUV/soft X-ray background, obtained with an EUV telescope on the Apollo-Soyuz mission. The principal results may be summarized as follows: (1) an intense background flux exists down to energies of 100 eV (4.0 plus or minus 1.3 photons/sq cm/sec/sr/eV average diffuse flux); (2) the Apollo-Soyuz data alone places lower and upper limits on single-temperature models for EUV-emitting interstellar gas for the log T range of 5.1-6.0; and (3) the allowed range would have to be restricted to log T of 5.1-5.6 for the Cash, Malina, and Stern (1976), Burstein et al. (1977), and Apollo-Soyuz data sets to satisfy a single-temperature model for the background at not greater than 280 eV.
