Table 2

Assumed survey parameters for ground-based I- and K-band wide-area surveys, as well as an H-band space-based survey.

I-band (Ground) K-band (Ground) H-band (Space)

umax 1 1 1 and 3
μsky [mag/arcsec2] 19.7 13.0 21.5
θpsf [arcsec] 1.0 1.6 0.4
mzp 20.4 24.6 24.9
texp [s] 180 60 54

Notes. For the ground-based I and K-band surveys texp is set so that mzp corresponds to the survey limiting magnitude for 4% photometric precision. The values for the H-band space-based survey are based on the propsed Euclid ExELS survey and are taken from Table 2 of Penny et al. (2013).
