Abstract (from CDS):

We present the full public data release (PDR-2) of the VIMOS Public Extragalactic Redshift Survey (VIPERS), performed at the ESO VLT. We release redshifts, spectra, CFHTLS magnitudes and ancillary information (as masks and weights) for a complete sample of 86 775 galaxies (plus 4732 other objects, including stars and serendipitous galaxies); we also include their full photometrically-selected parent catalogue. The sample is magnitude limited to iAB≤22.5, with an additional colour-colour pre-selection devised as to exclude galaxies at z<0.5. This practically doubles the effective sampling of the VIMOS spectrograph over the range 0.5<z<1.2 (reaching 47% on average), yielding a final median local galaxy density close to 5x10–3h3/Mpc3. The total area spanned by the final data set is ~=23.5deg2, corresponding to 288 VIMOS fields with marginal overlaps, split over two regions within the CFHTLS-Wide W1 and W4 equatorial fields (at RA~=2 and ~=22h, respectively). Spectra were observed at a resolution R=220, covering a wavelength range 5500-9500Å. Data reduction and redshift measurements were performed through a fully automated pipeline; all redshift determinations were then visually validated and assigned a quality flag. Measurements with a quality flag ≥2 are shown to have a confidence level of 96% or larger and make up 88% of all measured galaxy redshifts (76552 out of 86775), constituting the VIPERS prime catalogue for statistical investigations. For this sample the rms redshift error, estimated using repeated measurements of about 3000 galaxies, is found to be σz=0.00054(1+z). All data are available at http://vipers.inaf.it and on the ESO Archive.
