J/ApJ/566/744       EEMSS new X-ray clusters                 (Lewis+, 2002)

New X-ray clusters in the EINSTEIN Extended Medium-Sensitivity Survey. I. Modifications to the X-ray luminosity function. Lewis A.D., Stocke J.T., Ellingson E., Gaidos E.J. <Astrophys. J. 566, 744 (2002)> =2002ApJ...566..744L
ADC_Keywords: Clusters, galaxy ; X-ray sources Keywords: galaxies: clusters: general - surveys - X-rays: general Abstract: The complete ensemble of Einstein Imaging Proportional Counter (IPC) X-ray images has been reprocessed and reanalyzed using a multiaperture source detection algorithm. A catalog of 772 new source candidates detected within the 38' diameter central regions of the 1435 IPC fields comprising the Extended Medium-Sensitivity Survey (EMSS) has been compiled. By comparison, 478 EMSS sources fall within the same area of sky. A randomly selected subsample of 133 fields was examined; 73 sources were detected and compared with 49 original EMSS sources in the same region of sky. File Summary:

Note (1): An entry of zero indicates a value less than the detection threshold limit of 2.5. Note (2): Identification based on all the data in Tables 4-6 as follows: C = cluster of galaxies X = not a cluster of galaxies; C: = possible cluster of galaxies If there is no entry, no definitive determination is possible at this time.
