Galaxy And Mass Assembly (GAMA): Curation and reanalysis of 16.6k
  redshifts in the G10/COSMOS region
  We discuss the construction of the Galaxy And Mass Assembly (GAMA) 10h region
(G10) using publicly available data in the Cosmic Evolution Survey region
(COSMOS) in order to extend the GAMA survey to z~1 in a single ~1 deg^2 field.
In order to obtain the maximum number of high precision spectroscopic redshifts
we re-reduce all archival zCOSMOS-bright data and use the GAMA automatic
cross-correlation redshift fitting code autoz. We use all available redshift
information (autoz, zCOSMOS-bright 10k, PRIMUS, VVDS, SDSS and photometric
redshifts) to calculate robust best-fit redshifts for all galaxies and visually
inspect all 1D and 2D spectra to obtain 16,583 robust redshifts in the full
COSMOS region. We then define the G10 region to be the central ~1deg^2 of
COSMOS, which has relatively high spectroscopic completeness, and encompasses
the CHILES VLA region. We define a combined r < 23.0mag & i < 22.0mag G10
sample (selected to have the highest bijective overlap) with which to perform
future analysis, containing 9,861 sources with reliable high precision
VLT-VIMOS spectra. All tables, spectra and imaging are available at:
