RASSWD - ROSAT All-Sky Survey: White Dwarves
This database lists all white dwarf stars, both previously-cataloged and
newly discovered, which have been detected in the ROSAT All-Sky
Survey. The positions and count rates of the X-ray sources associated
with each star are given, as well as spectral types and other star
names for those stars which have been previously cataloged.
The database also lists distances estimated via Balmer line profile fitting,
corrected (for IS absorption) X-ray luminosities, and each star's
contribution to the X-ray luminosity function for all DA white dwarfs
which were detected in the ROSAT All-Sky Survey. This catalog is refered to
as the 'RASS Catalog of White Dwarfs' not the 'ROSAT All-Sky Survey Catalog
of White Dwarfs' in the XrayBrowse database system.

Note on RX J2034.9-2734, a '+' indicates neither photometry nor good
Note on count rate, a '+' indicates detection also made in hard band;
should be treated as upper limit.
