Description:
The catalog of isolated galaxies is defined on the basis of the
Palomar Sky Survey. It contains 1051 isolated galaxies with apparent
magnitudes brighter than 15.7 and north of declination -3°.
Compared to the original version published in 1973 (Comm. Special
Astrophys. Obs. of USSR, No. 8), new data about the morphological
types, the isolation class, and the radial velocities have been added.
The catalog includes running numbers for the galaxies, equatorial
coordinates, isolation classes, apparent magnitudes, morphological
types, major axes, axial ratios, and radial velocities.

Historical Remarks:
The (CIG) was received by the Astronomical Data Center (ADC), NASA
Goddard Space Flight Center, from the Centre de Donnees Astronomiques,
Strasbourg (CDS), in December 1986. The original tape consisted of two
text files, one containing the catalog data and another containing a
short explanation of the catalog fields and the list of radial
velocity source references. The only change made to the catalog file
was to delete blank columns to reduce the record size from 65 to 52
bytes.
Acknowledgements:
The original ADC documentation by Anne C. Raugh (1987) was used to create
this ReadMe file.
