The
following 5 s K limiting magnitude
table is based on UFTI tabulated sensitivites, corrected for a WFCAM assumed
fwhm of 0.6". A 20% overhead is also assumed for target acquisition
and microstepping. An average of 10 hours per night is assumed, and no
allowance for bad weather has been made. J and H limits for the same field-size/time
will be approximately 1.1 and 0.4 magnitudes fainter.
