Principal Galaxies Catalogue
The Catalogue of Principal Galaxies (PGC) is an astronomical catalog published in 1989 that lists B1950 and J2000 equatorial coordinates and cross-identifications for 73,197 galaxies. 40,932 coordinates (56%) have standard deviations smaller than 10″. A total of 131,601 names from the 38 most common sources are listed. Available mean data for each object are given:[2]
- 49,102 morphological descriptions,
- 52,954 apparent major and minor axis,
- 67,116 apparent magnitudes,
- 20,046 radial velocities and
- 24,361 position angles.
