"The ROSAT ALL-SKY SURVEY FAINT SOURCE CATALOGUE (RASS-FSC) has been
released and is available through the World Wide Web
(URL http://wave.xray.mpe.mpg.de/rosat/catalogues/rass-fsc/)
and via anonymous ftp (host ftp.xray.mpe.mpg.de, directory 
rosat/catalogues/rass-fsc).

This catalogue is derived from the all-sky survey performed during the
ROSAT mission in the energy band 0.1 - 2.4 keV. 105.924 sources are 
catalogued and represent the faint extension to the RASS bright source 
catalogue (RASS-BSC,cf. IAUC 6420, Voges et al. 1999, A&A 349,389). The 
sources have a detection likelihood of at least 7 and contain at least 
6 source photons. (The likelihood of source detection is defined as 
L =-ln (1-P) , with P = probability of source detection).

For each source we provide the ROSAT name, the position in equatorial
coordinates, the positional error, the source countrate and error, the
background countrate, exposure time, date of observation, two 
hardness-ratios and errors, extent and likelihood of extent, and 
likelihood of detection. 

Additional information about the catalogue can be obtained from the ROSAT
web page given above.
