Total usable exposure time from the GTO programme.

NB118 [s] J [s]

paw6 23 800 6240
paw5 24 080 6000
paw4 24 080 6000

stack 47 973 12 160

Notes. The total usable exposure time is listed, i.e. after discounting one NB118 exposure rejected in the visual inspection (Sect. 3.4) and 12 J-band exposures not delivered by CASU (Sect. 3.2). The exposure time for each of the 3 partially overlapping pawprint positions is given (cf. Fig. 2), as well as the typical exposure time per pixel in the stack, calculated as 2/3 times the sum over all pawprints.
