On the Search for Soft X-ray and Optical Counterparts of Selected COS-B γ -ray Sources
Abstract
The reported study involves a status report on an exploratory, totally unbiased, mapping of five COS-B sources (2CG 121+04, 2CG 135+01, 2CG 195+04, 2CG 218-00, 2CG 284-00) chosen to be in regions of the Galaxy as uncrowded as possible and easily accessible by the Einstein Observatory. Graphs are presented to show the X-ray coverage of 2CG 121+4, 2CG 135+1, and 2CG 195+4. Four adjacent pointings are shown covering the erro box of 2CG 121+4, an example of an 'empty' region, where no X-ray sources are evident. An example of a 'crowded' region is also presented.
