Marston (Drake University) and Ronald O. Marzke (CfA and Dominion Astrophysical Observatory | | Abstract: | We present the results of a complete Einstein Imaging Proportional Counter (IPC) X-ray survey of optically-selected galaxies from Shapley-Ames Catalog, Uppsala General Catalog and the European Southern Observatory Catalog. X-ray fluxes for 1018 galaxies have been surveyed, 21% of which are detected. 827 galaxies have either independent distance estimates or radial velocities. Associated optical, redshift and distance data has been assembled. The five large data tables in the paper are in easily-accessible ascii formats with an ADC-style README file, for easy electronic data handling. The accuracy of the X-ray fluxes has been checked in three different ways; all are consistent with the derived X-ray fluxes being of $le$0.1 dex accuracy. In particular, there is agreement with previous published X-ray fluxes for galaxies in common with Roberts et al. (1991) and Fabbiano et al. (1992). The data presented here will be used in further studies to characterize the X-ray output of galaxies of various morphological types and thus to enable the determination of the major sources contributing to the X-ray emission from galaxies. | | Source: | arXiv, astro-ph/9612188 | | Services: | Forum | Review | PDF | Favorites | |
