VizieR Online Data Catalog: LARGESS survey (Ching+, 2017)
Abstract
We have compiled the Large Area Radio Galaxy Evolution Spectroscopic Survey (LARGESS) catalogue, a new, large data set designed to study the evolution and environments of high- and low-excitation radio galaxies (HERGs and LERGs) out to z~0.8. The catalogue contains 19 179 radio sources detected by the FIRST survey that have an SDSS optical counterpart with imod<20.5. We have obtained new good-quality optical spectra for over 5000 LARGESS objects, and adding these to lower redshift archival data means that 10856 LARGESS objects currently have a reliable optical redshift.
