Scientific paper

Two clusters of galaxies have been observed with Exosat to map the distribution of cool gas. For A 1367 the two brightest sources found by the Einstein Observatory were detected. The identification of a X-ray source with a blue object near NGC 3842 was confirmed. By comparing the Exosat and the Einstein Observatory count rates it can be stated that either the source is variable, or that the HI column density is low, and the spectrum is either a power law with a spectral index greater than 1.5, or thermal with temperature below 6 million K. For A 1060 the classification from optical data of NGC 3311 as the dominant galaxy was confirmed, but no evidence was found for a central source as inferred from the Einstein Observatory data. An accretion rate of 10 solar masses/per year was derived.
