Limiting 3σ continuum sensitivity per spaxel and spectral resolution element as a function of the average continuum S/N at the half-light radius (HLR). The corresponding broadband surface brightness limits in r (V500) and g (V1200) are indicated on the right y-axis. The limiting continuum sensitivity and the S/N were computed from the median signal and noise in the wavelength region 4480–4520 Å and 5590–5680 Å for the V1200 and V500 data, respectively.
