Comparison of the VVDS-Deep with the SAM redshift distributions for 17.5 < I_AB < 24 galaxies. The VVDS-Deep N(z), while including only flag 2 to 9 galaxies, is shown with the solid thin histogram. The thick histogram corresponds to the corrected N(z) in the VVDS-Deep when accounting for the observational biases of the survey (see text for details). The solid curve and associated shaded area are the mean and the 1σ field-to-field dispersion among the Omocks, while the dotted curve is the mean prediction of the Cmocks.
