Distribution of the galactic compact x-ray sources: A statistical analysis

Upon examining the matter of completeness of the Uhuru sample, it is found that a source having L/subx/=1036 erg s-1 could not be detected from a distance beyond the galactic center, and only sources having L/subx/approximately-greater-than1037 erg s-1 should be detectable everywhere in the Galaxy. It is concluded that a significant number of weaker sources should be found by a detector with a better angular resolution than the Uhuru, and that the concentration of sources at longitudes near the galactic center reflects a real concentration of the sources toward the center of the Galaxy
