An Analysis of BeppoSAX LECS Observations of Extreme-Ultraviolet Emission in Clusters of Galaxies

Kaastra et al. have used the BeppoSAX LECS instrument to search for excess extreme-ultraviolet (EUV) emission in A2199. They claim that the results obtained confirm an independent report of an excess EUV emission in this cluster by Lieu et al. Using an in-flight-derived procedure that is better suited to the analysis of extended sources and that avoids uncertainties related to ground-based calibrations for the overall detector sensitivity profile, we find no excess EUV emission in A2199. We also used these procedures to search for an EUV excess in A1795, but no excess was found.
