Description:
The catalogue is an extension of the catalogue compiled by
Mathewson and Ford (1970MmRAS..74..139M 1970MmRAS..74..139M) and the list by
Klare and Neckel (1977A&AS...27..215K 1977A&AS...27..215K).

Note (1): names starting by + or - are DM (BD, CD, CPD) designations;
names starting by a digit are HD numbers.
Note (2): this field was computed from GLON and GLAT for stars from
Reference 6 (see Historical Notes)
Note (3): "II-" stands for "II-III", and "-IV" stands for "III-IV"
Note (4): References are
0: unidentified

Note (5): 2 stars were corrected in December 1997, marked by an
asterisk in this position (see Historical Notes)

Historical Notes:
* 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.
