VIPERS cone diagrams for the fields W1 (top) and W4 (bottom). The left panels show the redshift-space positions of observed galaxies. The marker colour indicates the blue or red colour class and the marker size scales with B-band luminosity. The depth of the slice is 10 h^-1 Mpc. The orange line traces the field boundaries cut in the redshift direction at 0.6 <z< 1.0. At right we show a slice of the density field taken from one step in the Markov chain. It represents the anisotropic Wiener reconstruction from the weighted combination of galaxy tracers. The field is filled with a constrained Gaussian realisation. The field has been smoothed with a Gaussian kernel with a full width half maximum of 10 h^-1 Mpc. The colour scale gives the over-density value.
