ADC_Keywords: Stars, white dwarf;


Description:
    The catalogue includes all probale white dwarf and degenerate stars
    found in the Proper Motion and Faint Blue Star Surveys conducted by
    W.J. Luyten.

    As a guideline for the inclusion of stars into this catalogue, the
    author has used stars which present minimal values of
    H = m + 5 + 5 log µ (µ is the proper motion in arcsec/yr)
    which show the minimal H values according to the color class:

       b  13.5   f  15.5    g-k 17.7
       a  14.4   g  17.0     k  18.3

    Note that the columns containing the proper motion (µ and θ),
    as well as the notes, are not included in the present version.
