| # Detailed Description of III/215 : 7th Catalog of Galactic Wolf-Rayet stars (van der Hucht, 2001) |

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:
        The VIIth catalogue of galactic Population I Wolf Rayet stars provides
        improved  coordinates,  spectral types  and bv photometry  of known WR
        stars  and adds  71 new WR stars  to the previous  WR catalogue.  This
        census  of galactic  WR stars  reaches 227  stars,  comprising  127 WN
        stars,  87 WC stars,  10 WN/WC stars and 3 WO stars.  This includes 15
        WNL  and 11 WCL stars within 30 pc of the Galactic Center.  We compile
        and  discuss WR  spectral classification,   variability,  periodicity,
        binarity, terminal wind velocities, correlation with open clusters and
        OB  associations,  and correlation with H I bubbles,  H II regions and
        ring nebulae.  Intrinsic  colours and  absolute visual  magnitudes per
        subtype  are re-assessed for a re-determination of optical photometric
        distances  and  galactic  distribution  of  WR  stars.  In  the  solar
        neighbourhood we find  projected  on  the  galactic  plane  a  surface
        density of 3.3 WR stars per kpc2,  with a WC/WN number ratio of 1.5,
        and  a WR binary frequency (including probable binaries)  of 39%.  The
        galactocentric  distance (RWR)  distribution per subtype shows RWR
        increasing with decreasing  WR  subtype,   both  for  the  WN  and  WC
        subtypes.  This RWR  distribution  allows  for  the  possibility  of
        WNE->WCE and WNL->WCL subtype evolution.

        The successive catalogues of galactic WR stars are:
