摘要：

We have obtained a mosaic of CCD images of the Coma cluster in the V-band covering a region of approximately 0.4 degrees(2) around both central cluster galaxies NGC 4889 and NGC 4874. An additional frame of similar to 90 arcmin(2) was taken of the south-west region around NGC 4839. We derived a catalogue of 7023 galaxies and 4096 stars containing positions, central surface brightnesses and isophotal V-26.5 magnitudes. We estimate that data is complete up to V-26.5 similar to 22.5 and the surface brightness limiting detection value is mu similar to 24 mag/arcsec(2). In this paper we present the catalogue (available in electronic form alone(1)), along with a detailed description of the steps concerning the data reduction and quality of the computed parameters.
