- Description:
- This "catalog of principal galaxies" constitutes the basis of the
- "Third Reference Catalogue of Bright Galaxies" (RC3). It lists
- equatorial coordinates for the equinoxes 1950 and 2000 and cross
- identifications for 73197 galaxies. Of the 73197 galaxies, 40932 have
- coordinates with standard deviations of less than ten arcsec. Listed
- are 131,601 names from the 38 most common sources. These data are
- given when available: morphological descriptions, apparent major and
- minor axes, apparent magnitudes, radial velocities, and position
- angles.
