5σ magnitude limits of the catalogues in the Z- (top panel) and Y-bands (bottom panel). The colour scale is shown in each case. The completeness of the DR1 can be also checked on the maps, where the missing tiles appear in black. Exposure times in the bulge and disk fields are different (see Table 3), as a result the disk fields have deeper photometry. Similar maps for J, H and K_s photometry, and for the variability campaign are presented in Figs. 4 and 5.
