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 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.
Description:
Infrared imaging at J, H, and Ks was obtained using the IRIM camera,
with a 256x256 NICMOS3 HgCdTe array at the Kitt Peak National
Observatory (KPNO) 2.1m telescope on the night of 1993 April 7.
Optical data were obtained during service observations by G. Jacoby at
the KPNO 0.9m telescope on 1994 March 15 and 16 using a 20482 CCD
with 0.680" pixels.

be overestimated because of their large extent, preventing accurate
sky subtraction -- see Section 2.1 for details.
