Abstract:
Here we report results for two subsamples of early-type galaxies,
defined primarily by their morphologies in the F160W band, which were
selected from the NICMOS data down to H160AB<24.0. A primary subsample
is defined as the 34 galaxies with early-type galaxy morphologies and
early-type galaxy spectral energy distributions. The secondary
subsample is defined as those 42 objects that have early-type galaxy
morphologies with non-early-type galaxy spectral energy distributions.
Description:
The HDF-N was observed by NICMOS between UT 1998 June 13 and June 23,
when the HST secondary mirror was at the optimal focus for camera 3.
Our observations and data reduction will be described in detail
elsewhere (Dickinson et al., 2004, in preparation)
