Abstract:
We present near-infrared (H band) surface photometry of 170 galaxies,
obtained in 1997 using the Calar Alto 2.2 m telescope equipped with
the NICMOS3 camera MAGIC. The majority of our targets are selected
among bright members of the Virgo cluster, however galaxies in the
A262 and Cancer clusters and in the Coma/A1367 supercluster are also
included. This data set is aimed at complementing the NIR survey in
the Virgo cluster discussed in Boselli et al. (1997A&A...324L..13B 1997A&A...324L..13B)
and in the Coma Supercluster, presented in Papers I, II and III of
this series. Magnitudes at the optical radius, total magnitudes,
isophotal radii and light concentration indices are derived.
