Detailed Description of J/A+A/316/147 :
Catalogue of ROSAT White Dwarfs (Fleming+ 1996)

Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

Description:
    Table1 lists all white dwarf stars, both previously-catalogued 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 catalogued.
    Table2 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.
