Beginning of ReadMe : IX/12 The WGACAT version of ROSAT sources (White+ 1995) ================================================================================ The WGACAT version of the ROSAT PSPC Catalogue, Rev. 1 White N.E., Giommi P., Angelini L. <HEASARC, Code 660, LHEA/GSFC, Greenbelt (1995)> ================================================================================ ADC_Keywords: X-ray sources Mission_Name: ROSAT Description: WGACAT is a catalogue of point sources generated at HEASARC from all the ROSAT PSPC (Position Sensitive Proportional Counter) pointing observations from Feb 1991 to March 1994. These were the files available in the public archive at HEASARC as of September 1994. This catalog is an independent research effort aimed at releasing as quickly as possible a list of sources detected by ROSAT in its pointed phase to: (1) identify the detected sources, (2) ensure their timely observation by currently active X-ray missions e.g. ASCA, (3) to search for objects which show exceptional time variability and spectral properties and (4) to provide an independent check of the detection technique used in the official ROSAT project (SAS) processing. WGACAT stands for N.E. White (HEASARC/GSFC). P. Giommi (ESA), and L. Angelini (HEASARC/GSFC)
