Comparison of the magnitude counts in the VDIS I-band with SAM predictions and previously reported measurements by Postman et al. (1998) in the KPNO survey, Leauthaud et al. (2007) in the COSMOS-ACS field, and Metcalfe et al. (2001) in the Hubble Deep Field-North & South. The VVDS-Deep counts are shown with the empty squares and the error bars correspond to their associated Poisson errors. The solid curve and associated shaded areas are respectively the mean and the 1σ, 2σ, and 3σ field-to-field dispersions among Cmocks samples.
