VizieR Online Data Catalog: VIPERS spectroscopic redshifts (PDR-2) (Scodeggio+, 2018)

Final public release of complete VIPERS galaxy catalogue of ~90,000 redshifts (PDR-2)

The "VIMOS Public Extragalactic Redshift Survey" (VIPERS) is a completed ESO Large Program that has mapped in detail the spatial distribution of normal galaxies over an unprecedented volume of the z~1 Universe. It used the VIMOS spectrograph at the 8~m Very Large Telescope to measured spectra for more than 90,000 galaxies with red magnitude I(AB) brighter than 22.5 over an overall area of nearly 24 square degrees. At this redshift, VIPERS fills a unique niche in galaxy surveys, optimizing the combination of multi-band accurate photometry (5 bands from the CFHT-LS, plus Galex-NUV and NIR from WIRCAM and other facilities over most of the area) with the multiplexing capability of VIMOS. A robust color-color pre-selection allowed the survey to focus on the 0.5<z<1.2 redshift range, yielding an optimal combination of large volume (5x10⁷h^-3Mpc³) and high effective spectroscopic sampling (46% on average). VIPERS has produced a data set that in many respects represents for the first time the equivalent at z~1 of the large surveys of the "local" (z<0.2) Universe built at the beginning of this century (SDSS and 2dFGRS).
