Description:
   This catalog is survey of OB stars in the Southern Milky Way done as part
   of work performed from 1961-963 at the Uppsala Southern Station at Mount
   Stromlo. Objective prism plates from a 50/65cm Schmidt telescope were 
   searched for faint OB stars between galactic longitudes lII=310 degrees and 
   lII=334 degrees, resulting in a catalog of 483 objects. The data file 
   contains a running number, CD, CPD, HD numbers, RA and Dec (1950.0), 
   magnitude from CD or CPD, ptm magnitude and spectral class from HD.

Note on CPDzone,CPDnum,CDzone,CDnum:
    Follows convention of AD catalog, i.e. for stars whose declination in 1875
    was north of -52 degrees, the CD was used.  For stars south of this limit
    the CPD was used.  If a star was not found in the appropriate catalog, but
    was present in the other, the number from the other was used.  A total of
    55 stars were not present in either catalog.  Their coordinates were 
    estimated from the direct plates taken with the Uppsala Schmidt telescope,
    using plots of CD or CPD stars to an accuracy of about 1 arcminute.
