Description:
The catalog contains data and bibliographical citations for all 70
associations of the second edition of the "Catalogue of Star Clusters
and Associations (CSCA)" edited by Alter et al. (1970) which includes
data for open clusters, associations, globular clusters and
extragalactic objects up to 1967 and "Supplement to the CSCA" by
Ruprecht et al. (1982), which contains the supplementary data up to
the end of 1973. Thus, the literature is covered through 1973. The
catalog includes the years of the literature, references, authors,
abbreviated journal references, diameters, distances and color indices
of the associations, number of stars and spectral types of the stars
in the associations, and identification of the Palomar Observatory Sky
Survey Chart on which the association appears.

--------------------------------------------------------------------------------
Note (1): the position was added at CDS for additional associations, i.e.
ASS names with decimal figures. These positions have generally
less accuracy.
Note also that the last association ASS-70 has no position:
it lays over tens of degrees.

Note on Misc:
The aggregated data and notes combined into the the Misc column do not
follow a strict column structure. For many records, the notes start
at the beginning of this field (byte 52). Other records contain some
or all of the following subfields loosely adhering to the byte ranges
shown:
52- 55 DIST: Distance of the association (pc)
57- 60 LD: Linear diameter of the association (pc)
65- 67 N: Number of stars in the association
69- 74 MG: Type of photometric magnitudes
76- 81 CI: Color index of the association
83- 87 SP: Spectra
88- 92 P: Positions
94-141 NOTE: Notes
--------------------------------------------------------------------------------
Remarks:
The original catalog contained multiple record formats in one file.
The file "names.dat" has been created from the first record per
association. The file "assoc.dat" has been created from second
records; missing positions were filled with approximative values found
in the literature. The file "refs.dat" was created from the third and
following records for each association.
