Description:
  This catalogue includes the Open Clusters of the supplement up to
  1973 of the "Catalogue of Star Clusters and Associations" by Alter
  G., Ruprecht J., Vanysek V., Budapest 1970. 

  The file "main.dat" contains the original data. For each cluster, 
  the first line contains the running number (OCL) followed by 
  various designations. The first five figures represent the galactic 
  longitude (in 0.01degree), 'N' or 'S' for North or South galactic 
  hemisphere, and galactic latitude (in 0.01degree). 

  The second line contains the 1950 coordinates, the 50-yr precession,
  the galactic direction cosines and the position on the POSS charts. 

  For each cluster a number of bibliographic records follow containing:
               YEAR: Year of the literature reference
               NAME: Author
        PUBLICATION: Reference
                 AD: Angular diameter of the cluster in arc minutes
               DIST: Distance of the cluster (pc)
                 LD: Linear diameter of the cluster (pc)
                  N: Number of stars studied
                 CI: Color index
                 SP: Spectra
                  P: Positions
                 RV: Radial velocity (km/s)
                 MT: Integrated magnitude
               NOTE: Notes

  The file "clusters" has been created from first and second lines; 
  missing equatorial coordinates were derived from the galactic
  ones.

Note on GLON, GLAT, RAh, RAm, DE-, DEd, DEm: 
  The position is missing for the last 5 moving clusters.               
  The equatorial coordinates have been computed from galactic           
  ones for additional clusters, i.e. OCL names with decimal figures.

  The file "clusters" was generated at CDS as explained above;                
  the longitude of OCL-105 was corrected, and also the right                  
  ascension of OCL-279. At the ADC the Declination of OCL-843.1 
  and of OCL-852.1 were corrected (Jul 1996).
