Description:
We present a CCD catalogue of 7023 galaxies and 4096 stars in the
region of the Coma cluster containing positions, central surface
brightnesses and V magnitudes (isophote 26.5). We estimate that data
is complete up to isophotal V magnitude 22.5 and the surface
brightness limiting detection value is approximately 24 mag/arcsec2.

Note (1): Classification of the object as follows:
1: Star
0: Galaxy
Note (2): GMP number, when available. The correspondence was obtained by
cross-correlating positions, which results in inevitable ambiguities
in some cases. That is why there are 4 entries doubled. In addition,
there are also several other entries which are attributed the same
GMP number. Details are given in the paper.
Note (3): GMP catalogue used for the matching:

Note (4): Heliocentric radial velocity are taken from:
