Notes.

^(a)

In-band seeing estimated From the PSF FWHM measured in long-exposure images. The final angular resolution is ∼0.2″ in all three bands.

^(b)

Number of pointings.

^(c)

Number of exposures per pointing.

^(d)

Integration time for each exposure. The total integration time of each observation is given by N × NDIT × DIT.
