Abstract
We present extensive and accurate photometry in the near-infrared H band of a complete sample of objects in an area of about 400 arcmin(2) toward the Coma cluster of galaxies. The sample, including about 300 objects, is compl ete down to H similar to 17 mag, the exact value depending on the type of m agnitude (isophotal, aperture, Kron) and the particular region studied. Thi s is six magnitudes below the characteristic magnitude of galaxies, well in to the dwarfs' regime at the distance of the Coma cluster. For each object (star or galaxy) we provide apertures magnitudes computed within five diffe rent apertures, the magnitude within the 22 mag arcsec(-2) isophote; the Kr on magnitude and radius, magnitude errors; as well as the coordinates, the isophotal area, and a stellarity index. Photometric errors are 0.2 mag at t he completness limit. This sample is meant to be: the zero-redshift referen ce for evolutionary studies of galaxies.
