Two important features of the HDF-S distinguish it from the HDF-N: the
campaign included parallel observations by the three main HST
instruments - WFPC2, STIS and NICMOS - and the HDF-S location was
selected to place a bright z=2.24 quasar in the STIS field of
view. The HDF-S observations consist of WFPC2 images in filters close
to U, B, V, and I, a deep STIS image of the field surrounding the
quasar, spectroscopy of the quasar with STIS from 1150-3560 Angstrom,
and deep imaging of an adjacent field with NIC3 at 1.1, 1.6 and 2.2
micron. All of the deep fields data were fully reduced and made
publicly available within two months of the observations, and we
describe here the selection of the fields and the observing strategy
that was employed. The detailed descriptions of the data and the
reduction techniques for each field, together with the corresponding
source catalogs, appear in separate papers.
