Abstract:
We present near-infrared H-band (1.65µm) surface photometry of 297
galaxies (mostly) in the Coma Supercluster obtained with the Arcetri
NICMOS3 camera, ARNICA, mounted on the Gornergrat Infrared Telescope.
Magnitudes and diameters within the 21.5mag/arcsec2 isophote,
concentration indices, and total H magnitudes are derived. Combining
these observations with those obtained similarly using the Calar Alto
telescopes (Paper I, J/A+AS/120/489) we find a strong positive
correlation between the near-infrared concentration index and the
galaxy H-band luminosity, and we analyze the consequent dependence of
near-infrared growth-curves on H-band luminosity.
For a description of the H band photometric system, see e.g. GCPD/59
