Up: Near infrared surface

5. Summary

We have obtained NIR surface photometry of a subsample of 102 mainly late-type galaxies in the Virgo cluster complete to tex2html_wrap_inline2666. Magnitudes, diameters, concentration indices within the 21.5 and 22.0 mag arcsectex2html_wrap_inline2668  isophote and total H and K' magnitudes are derived.

The NIR light profiles cover a substantial fraction of the optical diameter and in most cases are consistent with pure disks. Substantial bulges, producing tex2html_wrap_inline2674, are found among the reddest and most early type objects.

The overall B and K' luminosity distributions are consistent with tex2html_wrap_inline2680, but there is a trend, more closely linked to galaxian mass than to morphology, for the galaxies to become bluer with progressively fainter K' magnitudes.
