VizieR Online Data Catalog: The CASBaH galaxy redshift survey (Prochaska+, 2019)

We retrieved all photometric sources in the SDSS-DR12 catalog within 2° of the nine quasar fields, requesting Petrosian magnitudes and errors. We then cross-matched these to the spectroscopic catalog and cut on z>0.001666 (v>500km/s) to trim stars. These data form the primary public data set integrated within our CASBaH database.

For seven fields, we obtained deep multi-band (UBVI or griz) images with the Large Binocular Camera (LBC) on the Large Binocular Telescope (LBT) between 2009 June and 2011 May. See section 2.2.2.

For all of the MMT/Hectospec data collected in our CASBaH survey, we employed an identical setup, yielding R~1000 with wavelength coverage λ_ob~3700-9200Å. The observations, spanning 2011 Jan 25 to 2012 Mar 14, used three or more exposures with times ranging from 900 to 1800s each, for a total exposure of 3600s or 5400s. See section 2.3.1 and 3.1.1.

For the Keck/DEIMOS observations --spanning 2012 Nov 14 to 2013 May 8-- of the CASBaH target fields, the setup yields a spectral resolution R~1600 with wavelength coverage of λ_ob~5000-10000Å. See section 2.3.2 and 3.1.2.
