Abstract:
We present a catalog of morphological and color data for galaxies with
21<I_814<25mag in the Hubble Deep Field (Williams et al. 1996, in
Science with the Hubble Space Telescope II). Galaxies have been
inspected and (when possible) independently visually classified on the
MDS and DDO systems. Measurements of central concentration and
asymmetry are also included in the catalog. The fraction of
interacting and merging objects is seen to be significantly higher in
the Hubble Deep Field than it is among nearby galaxies. Barred spirals
are essentially absent from the deep sample. The fraction of
early-type galaxies in the Hubble Deep Field is similar to the
fraction of early-types in the Shapley-Ames Catalog, but the fraction
of galaxies resembling archetypal grand-design late-type spiral
galaxies is dramatically lower in the distant HDF sample.

Note on n_ID:
The 42 high-z candidates with red UV-optical colors (U_300-B_450>-0.2)
and blue optical-near IR colors (V_606-I_814>-0.6), indicating the
possible presence of the Lyman discontinuity in the U_300-band
spectral energy distribution (Steidel et al., 1996ApJ...462L..17S),
are indicated by an asterisk in this column.
Note on Xpos, Ypos:
Pixel coordinates on the version 2 "drizzled" HDF frames released
by STScI. The first digit in the ID numbers corresponds to the
WF/PC2 chip on which the object lies. Note also that positions
were originally measured on the version 1 drizzled images, and
were converted to version 2 coordinates using (x,y)_v1=76+(x,y)+v2
(M. Dickinson, private communication).
Note on Conc:
Color concentration measure from Abraham et al., (1996MNRAS.279L..47A).
Note on RSE:
Visual classification by RSE into three large bins
(E = elliptical, S=spiral, P=irregular/peculiar/merger).
Note on vdB:
Visual classification by vdB on the numerical "MDS system" used by
RSE to classify the data in Glazebrook et al, (1995MNRAS.275L..19G)
and described in detail in Abraham et al. (1996ApJS..107....1A).
Note on Desc:
Galaxy classification by vdB on the DDO system. All uncertain
classifications are followed by a colon.
Note on Note:
Notes on the DDO classifications and remarks on the colors of individual
galaxies are given:
