Description:
  The catalog is a compilation from the literature of all O-type stars
  for which spectral types, luminosity classes, and UBV photometry
  exist.  The catalog contains 765 stars, for each of which designation
  (HD, DM, etc.), spectral type, V, B-V, absolute visual magnitude,
  absolute bolometric magnitude, cluster membership, distance, galactic
  coordinates, and source references are given.  In addition, the
  authors have included derived values of absolute visual and bolometric
  magnitudes, and distances. 

  The Catalog of Galactic O-Type Stars (Garmany, Conti and Chiosi 1982)
  is a compilation from the literature of all O-type stars for which
  spectral types, luminosity classes and UBV photometry exist.  Most of
  the entries come from Cruz-Gonzalez, et al. (1974) and Humphreys
  (1978), with additional stars from Garrison and Kormendy (1976),
  Garrison, Hiltner and Schild (1977), Garrison and Schild (1979),
  Feinstein, Marraco and Muzzio (1973), Feinstein, Marraco and Forte
  (1976), and Moffat, FitzGerald and Jackson (1979).

Note on Dist:
   Distance computed from star's distance modulus, assuming an
   interstellar absorption of A(V)=3E(B-V). 

Note on GLONd, GLATd, GLONm, GLATm:
   The galactic longitude and lattitude are given in whole degrees and 
   arc minutes rather than the frequently used decimal degrees. The sign 
   of the Galactic lattitude is always in byte 68.

Note on r_ID: 
   The following list are references for the codes for primary source,
   additional cluster membership, additional spectral types, and
   additional photometry. The additional sources were generally used
   in cases where the data were missing or inadequate in the primary
   source or where there is disagreement among the papers consulted.

Remarks, Modifications, Acknowledgments and References:

  The Catalog of Galactic O-Type Stars was received on magnetic tape
  from Dr. C. D. Garmany of the University of Colorado on April 15,
  1982.  The following modifications were made to the format in order to
  make the star designations uniform (so that the file can be sorted by
  star name if desired) and to make the data records more homogeneous
  and easier to process by other users. 

  1.The B-V data were made uniform by attaching preceding zeros where 
    they were not present and by moving minus signs so that they always 
    occur in byte 65.

  2.Minus signs for the bolometric magnitude field were moved in order 
    to always occur in byte 47.

  3.Cluster and association membership codes had been written as -0 if 
    not present.  These were changed to blanks.

  4.Signs were attached to all Galactic latitude values, uniformly in 
    byte 68.

  5.Source codes of 0 were changed to blanks so that the string of 
    codes in bytes 75-78 contains digits only where reference codes 
    are present.

  6.The star designation field was expanded to 18 bytes so that the
    identifications could be made uniform.  The format was then changed by
    preparing a separate data set containing only the identifiers and
    editing all designations to contain catalog or cluster specifications
    in bytes 1-8, star numbers in bytes 9-16, and component
    identifications in bytes 17-18.  The modified designation fields were
    then substituted back into the data file.  A sort of the catalog by
    star designation will now yield a data set with all similar
    designations together and properly ordered. 

  7.The asterisk signifying a new spectral classification made by the
    authors, formerly appearing at the beginning of a record, was moved to
    byte 19. 

  8.Three duplicate entries were removed after carefully checking,
    confirming their redundancy, and notifying the first author. 

  9.The blanks in byte 48 and byte 69 were replaced by zero's. (1994/11/14)

   of Galactic O-Type Stars on magnetic tape with a listing and
