2MASS J13003680+2818172 , the SIMBAD biblio

We present extensive and accurate photometry in the near-infrared H band of a complete sample of objects in an area of about 400arcmin² toward the Coma cluster of galaxies. The sample, including about 300 objects, is complete down to H∼17mag, 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 22mag/arcsec² isophote, the Kron magnitude and radius, magnitude errors, as well as the coordinates, the isophotal area, and a stellarity index. Photometric errors are 0.2mag at the completness limit. This sample is meant to be the zero-redshift reference for evolutionary studies of galaxies.
