ADC_Keywords: Clusters, galaxy ; Galaxy catalogs 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.

Number of galaxies in group 36- 39 F4.1 mag BrRmag ? Magnitude (red) of brightest galaxy in group 41- 45 F5.2 arcmin Size ? Size of group 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 and Heinz Andernach Acknowledgements: It is a pleasure to thank Heinz Andernach and Marion Schmitz for their careful verification of the catalog.
