Notes.
3σ magnitude limit measured in apertures of radius r = 1 arcsec × C where C = FWHMinst/FWHMFORS2/R − band is used to rescale the radius of the aperture depending on the PSF of the images relative to that of FORS2/R-band. The aperture radius r ranges from 0.10 arcsec to 0.80 arcsec for the observations listed in the table.
