Top panel: projected correlation functions of VIPERS galaxies in the redshift interval 0.5 < z < 1 for the individual W1 and W4 fields as well as for the combined sample. As a comparison, the ± 1σ dispersion among the mean  w_p(r_p) in the mocks is shown with the shaded region and the non-linear mass prediction in the assumed cosmology with the dotted curve. Bottom panel: relative difference between the measured w_p(r_p) in the W1 and W4 fields and the combined projected correlation function .
