On the low energy X-ray absorption of the Coma, Virgo and Perseus clusters.
Abstract
X-ray data from the soft and medium energy X-ray experiments (0.15-8 keV) on board ANS for the Coma, Perseus and Virgo Clusters are presented. The derived spectral parameters above 2 keV are in general agreement with the Uhuru, Ariel V and OSO-8 data. Due to the availability of a low-energy channel around 0.25 keV, further limits on the low energy absorption have been determined.
