A MORPHOLOGICAL CATALOG OF GALAXIES IN THE HUBBLE DEEP FIELD

We present a catalog of morphological and color data for galaxies with 21 < l(814) < 25 mag in the Hubble Deep Field (Williams et al. 1996). Galaxies have been inspected and (when possible) independently visual ly classified on the MDS and DDO systems. Measurements of central conc entration 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 spi rals are essentially absent from the deep sample. The fraction of earl y-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 drama tically lower in the distant HDF sample.
