WGACAT
     N. E. White, Laboratory for High Energy Astrophysics, Goddard Space
Flight Center (LHEA/GSFC); P. Giommi, European Space Information System,
European Space Research Institute; and L. Angelini,
LHEA/GSFC, report that WGACAT, a ROSAT catalogue of point sources, is now
available through HEASARC, the High Energy Astrophysics Science Archive
Research Center online service.  This catalogue, generated using the ROSAT
PSPC pointed data publicly available up to Sept. 1994, contains 50 000
detections and more than 45 600 individual sources; a total of 2624 fields
were searched.  WGACAT is an independent research effort aimed at
releasing as quickly as possible a list of sources detected by ROSAT in
its pointed phase to identify the detected sources.  Optical identification
of these x-ray sources is encouraged.  WGACAT can be accessed via HEASARC
by logging into legacy.gsfc.nasa.gov with the username xray.  Type
browse wgacat to access the catalogue.  WGACAT can also be accessed via
the anonymous ftp account on the same machine under the directory
rosat/wgacat/files and via the HEASARC WWW Browse interface under
http://heasarc.gsfc.nasa.gov/StarTrax/Browse.html by clicking on ROSAT and
then selecting WGACAT.  Send mail to wgacat@athena.gsfc.nasa.gov if you have
any questions regarding this catalogue.
