Beginning of ReadMe : IX/8 Second Catalogue of X-ray Sources (Amnuel+ 1982) ================================================================================ Second Catalogue of X-ray Sources Amnuel P.R., Gusenov O.H., Rakhaminov Sh.Yu. <Astrophys. Sp. Sci. 82, 3 (1982)> =1982Ap&SS..82....3A ================================================================================ ADC_Keywords: X-ray sources Description: The catalog is a compilation of X-ray sources containing 677 objects known as of 1979 September. X-ray data for 677 sources are the result of X-ray sky surveys by rockets, balloons, and satellites during 1964-1979. The sky survey is practically complete to X-ray intensities of nearly 4 micro-Jy in the 2-6 keV range. The current version does not include the investigation by HEAO 2. The catalog includes source names, positions of the maximum probability densities, date of the measurements, the type of measuring systems, the ranges at which the measurement was performed, maximum intensities for constant sources, and ratio of the maximum observed value of intensity to the minimum one for variable sources. The catalog is an update of the publication, by the same authors, in 1979ApJS...41..327A
