Number densities of VIPERS galaxies in the individual W1 and W4 fields and of CFHTLenS/VIPERS photometric redshift galaxies, as a function of redshift. The number densities of VIPERS galaxies are corrected for the survey incompleteness by weighting each galaxy in the counts by its associated inverse completeness weight wC. The solid curve corresponds to the model n(z) used in the analysis. It was obtained by randomly sampling galaxy redshifts within their Vmax (see text for details).
