Abstract:We present two wide-field catalogues of photometrically selected emission line galaxies (ELGs) at z~=0.8 covering about 2800deg^2^ over the south galactic cap. The catalogues were obtained using a Fisher discriminant technique described in a companion paper. The two catalogues differ by the imaging used to define the Fisher discriminant: the first catalogue includes imaging from the Sloan Digital Sky Survey and the Wide-field InfraredSurvey Explorer, the second also includes information from the South Galactic Cap U-band Sky Survey. Containing respectively 560045 and 615601 objects, they represent the largest ELG catalogues available today and were designed for the ELG programme of the extended Baryon Oscillation Spectroscopic ...(more)
Abstract: (hide)
The UgrizW and griW selections both use combined information from different photometric catalogues. The griW selection uses SDSS g, r and i bands as well as WISE infrared W1 information, while the UgrizW also includes SDSS z band as well as SCUSS U band. This section introduces the different photometric catalogues used as well as the algorithms defining the selections
