		<para>  * The tape was received at CDS in 1977 from the authors
  * February 1996: the catalogue was reformatted in the following way:
    => the Name of the stars have been changed from 8 to 10 bytes,
       inserting blanks between zone and numbers of DM designations;
    => the galactic longitude and latitude, originally in degrees and
       arc minutes, have been converted into decimal degrees ;
    => the missing equatorial positions (from Ref. 6) have been computed
       from the galactic position.
  * December 1997: errors communicated by Thomas  Szeifert,
    T.Szeifert@lsw.uni-heidelberg.de: the two stars -33 12242 and
    -29 13809 had a wrong position in the catalogue; the GLON, GLAT,
    and galPA values were corrected accordingly, and these two stars
    were set the n_galPA and moved to match the GLON ordering.</para></revision></revisions></history>
