Abstract:We present a set of UBVRIzJHKs photometry for 745 J+H-band-selected objects in a 22.5'x29.2' region centered on the core of the Coma Cluster. This includes 516 galaxies and is at least 80% complete to H=16, with a spectroscopically complete sample of 111 cluster members (nearly all with morphological classification) for H<14.5. For each object we present total Kron (1980ApJS...43..305K) magnitudes and aperture photometry. As an example, we use these data to derive color-magnitude relations for Coma early-type galaxies, measure the intrinsic scatter of these relations and its dependence on galaxy mass, and address the issue of color gradients.
