Description:
    The catalog is a compilation of ten published lists of compact groups
    of compact galaxies found on the Palomar Sky Survey red charts. The
    catalog contains 377 groups of compact galaxies and includes
    identifications, equatorial coordinates, numbers of constituent
    galaxies, magnitudes of the brightest member, sizes of the groups as a
    whole, and coefficients of relative compactness.

  47- 49  F3.1  ---     Cmpct    *? Coefficient of compactness
--------------------------------------------------------------------------------
Note on Ngal: in the published lists, this number was frequently
     stated as a range; these ranges were apparently converted to
     their median value.
Note on Cmpct: this coefficient is the ratio of the sum of the diameters of
     all the galaxies of the group to the diameter of the group as a whole.
     Note that this coefficient is rounded compared to the publications
     for objects 306 to 377.

Nomenclature Notes:
    Various acronyms are found in the literature to designate the objects
    from this catalogue:
    Shk    (recommended acronym, from first author's name)
    SCGG   (Shakhbazian, Compact Group of G)
    SHCG   (Shakhbazian, Cluster of G)

History:
  * The catalogue was received at CDS in 1986.
    It was checked and corrected against the published catalogue at
    Astronomical Data Center (ADC), NASA Goddard Space Flight Center,
    Greenbelt.
  * Further checks were performed in November 1993 by Marion Schmitz
    at IPAC <mschmitz@ipac.caltech.edu> and Heinz Andernach
    <hja@vilspa.esa.es>

Acknowledgements:
    It is a pleasure to thank Heinz Andernach and Marion Schmitz for
    their careful verification of the catalog.
