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.

Remarks:
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).
