Description VIPERS is the largest galaxy redshift survey conducted at ESO to date. This final redshift catalogue includes 91507 spectroscopic measurements, of which 86775 are galaxies, distributed over two equatorial areas of sky centered around RA=2 (W1 CFHTLS field) and RA=22 (W4 CFHTLS field). The data provide a sampling of galaxies and large scale structure at 0.5 < z < 1.2
