magnitude limits (for a total of 100 ks integration time per pointing) of AB <= 25 mag (for anunresolved object, signal-to-noise ratio = 5) in the optical filtersfrom the blue to 8300 Å, and from AB = 24.7 to 23.4 for the redderones. The limit in the NIR, for a total of 15 ks exposure time perpointing, is (in the Vega system) Ks ≈ 20 mag, H≈ 21mag, J≈ 22 mag.
