Description:
The catalog is a compilation of information for approximately 34000
galaxies found and examined on the Palomar Observatory Sky Survey
(POSS). Individual identifiers are assigned for about 29000 galaxies
and information on the remaining 5000 is present in the extensive
notes of the published catalogs (Vorontsov-Velyaminov et al.
1962-1968). The catalog is structured according to the POSS zones,
counting from the equator, and is numbered from +15 (corresponding to
+90 deg) to +01 (+06 zone) and +00 (equatorial zone) to -05 (-30
zone); the fields are numbered with increasing right ascension. The
catalog includes cross-identifications to the NGC (Dreyer 1888) and IC
(Dreyer 1895, 1908) catalogs, equatorial coordinates for B1950.0,
magnitudes, estimated sizes and intensities of the brighter inner
region and the entire object, and estimated inclinations.

13323(MCG+04-06-049)
- Error in "MajorAxis" parameter for record 19653(MCG+01-37-012)
* 22-Oct-1996: Gail L. Schneider (SSDOO/ADC)
- Error in "MCG" for record 4341 corrected
For: MCI+09-19-067 Read: MCG+09-19-067
* 09-Jan-2001: Units of Major/Minor Axises were reported as arcmin --
but are tenths of arcminutes.
