Received June 16; accepted October 6, 1999
We present extensive and accurate photometry in the near-infrared H band of
a complete sample of objects in an area of about 400 arcmin2 toward the
Coma cluster of galaxies. The sample, including about 300 objects, is
complete down to
mag, the exact value depending on the type of
magnitude (isophotal, aperture, Kron) and the particular region studied. This
is six magnitudes below the characteristic magnitude of galaxies, well into the
dwarfs' regime at the distance of the Coma cluster.
For each object (star or galaxy) we provide aperture
magnitudes computed within five different apertures, the magnitude within the
22 mag arcsec-2 isophote, the Kron magnitude and radius, magnitude
errors, as well as the coordinates, the isophotal area, and a stellarity
index. Photometric errors are 0.2 mag at the completness limit.
This sample is meant to be the zero-redshift reference for evolutionary
studies of galaxies.
Key words: galaxies: luminosity function, mass function -- galaxies: clusters: individual: Coma (=Abell 1656)
