Behavior of the empirically measured noise in apertures of varying size (solid line) vs. the expected one (dashed line), for the central part of the VV 29 F475W images, based on the drizzle parameters and the noise model of Casertano et al. (2000). As in the case of the HDFN, the measured noise is higher than the prediction. Similar behavior is observed in the other filters.
