Abstract

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 deg2 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 _1 deg2 of COSMOS, which has relatively high spectroscopic completeness, and encompasses the CHILES VLA region. We define a combined r < 23:0 mag & i < 22:0 mag 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: http://ict.icrar.org/cutout/G10.
