Abstract:
    We present a deep photometric (B- and R-band) catalog and an
    associated spectroscopic redshift survey conducted in the vicinity of
    the Hubble Deep Field-South. The spectroscopy yields 53 extragalactic
    redshifts in the range 0<z<1.4, substantially increasing the body of
    spectroscopic work in this field to over 200 objects. The targets are
    selected from deep Anglo-Australian Telescope prime-focus images
    complete to R<24, and the spectroscopy is 50% complete at R=23.

Description:
    Images in B and R were taken with the Anglo-Australian Telescope (AAT)
    prime-focus CCD camera (0.391"/pixel) in 1999 May at two pointings
    containing the Wide Field Planetary Camera (WFPC; AAT-WF) and Space
    Telescope Imaging Spectrograph (STIS; AAT-ST) fields. The
    spectroscopic observations were made with the AAT Low Dispersion
    Survey Spectrograph, and carried out over the nights of 1998 October
    13-16 at the AAT.

--------------------------------------------------------------------------------
Note (1): NULL entries throughout this table denote missing data primarily due
          to the B band data being less deep than the R band but also slightly
          different depth and coverage at the edge of the fields and differences
          in extraction due to the presence of strong straylight features. This
          table is not cleaned for sources lying in masked areas (i.e. in
          vignetted regions or along sites where stray light is strong) but the
          mask flag is included in the table.
Note (2): Parent image of the detection, defined as follows:
     WF = AAT-WFPC2 field;
     ST = AAT-STIS field;
     WS = Overlap region;
    WMS = Overlap region but masked in one of the fields.
Note (4): NULL means not detected.
Note (6): Photometric condition defined as follows:
     PH = photometric conditions (WF-B, WF-R, ST-R data);
     NP = non-photometric conditions where calibration using common sources
          detected in the photometric (WF-B) and non-photometric (ST-B)
          lying in the overlap region has been used.
Note (7): Generally <8 is reliable.
