Notes. Lines (L1–L6): information computed with the photometric data over a ~50 deg2 area within the CFHTLS/W1 field (density, overlap with LRGs identified using the cuts defined in Prakash et al. (2015), photometric redshifts statistics). Lines (L7–L8): number of 0.6 ≤ zspec ≤ 1.0 VIPERS galaxies passing the selection, and percentage of those having erg cm-1 s-2. Lines (L9–L14): spectroscopic information for the eboss6-7 plates observations covering an area of 8.82 deg2 (number of galaxies, percentage of observed galaxies, percentage of galaxies with unreliable zspec measurement, zspec statistics). Lines (L15–L16) present spectroscopic information for the eboss6-7 galaxies with a reliable zspec measurement with 0.6 ≤ z ≤ 1.0 (mean zspec, percentage of galaxies with erg cm-1 s-2, expected percentage of galaxies with catastrophic zspec estimation). For lines (L10–L16), we report in brackets the quantities derived from our spectroscopic observations for the Fisher_GRIW1OII and Fisher_GRZW1 selections: those quantities are biased because they are obtained from a non-random subsample constituted of objects passing the Fisher_UGRIZW1 or Fisher_GRIW1 selections.
