Abstract:
We report the results of an extensive imaging and spectroscopic survey
in the Great Observatories Origins Deep Survey (GOODS)-North field
completed using DEIMOS on the Keck II telescope. Observations of 2018
targets in a magnitude-limited sample of 2911 objects to RAB=24.4
yield secure redshifts for a sample of 1440 galaxies and active
galactic nuclei (AGNs) plus 96 stars. In addition to redshifts and
associated quality assessments, our catalog also includes photometric
and astrometric measurements for all targets detected in our R-band
imaging survey of the GOODS-North region.
Description:
To ensure timely access to a catalog of astrometric positions and
approximate magnitudes for completing the spectroscopy, we generated
our own independent catalog of sources in the GOODS-N field. We
acquired a series of 300s R-band exposures using DEIMOS in imaging
mode on Keck II during the night of 2002 December 30 (UT) and
complemented these with additional images obtained on 2003 February 02
(UT) to complete coverage of the full ACS imaging region. The
exposures were offset and dithered to compensate for the gaps in the
DEIMOS CCD mosaic.
