Abstract:
We present near-infrared H-band (1.65µm) surface photometry of 558
galaxies in the Coma Supercluster and in the Virgo cluster. This data
set, obtained with the Arcetri NICMOS3 camera ARNICA mounted on the
Gornergrat Infrared Telescope, is aimed at complementing, with
observations of mostly early-type objects, our NIR survey of spiral
galaxies in these regions, presented in previous papers of this
series. Magnitudes at the optical radius, total magnitudes, isophotal
radii and light concentration indices are derived. We confirm the
existence of a positive correlation between the near-infrared
concentration index and the galaxy H-band luminosity
