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.
