The 1σ sensitivity curves for the Gold sample in Table 2. The dashed and dotted lines show the 68% and 95% spread of the limits for the individual spectra, respectively, whereas the thick solid line shows the median 1σ sensitivity. The limits have not been corrected for the lensing magnification of each object, μ, listed in Table 2. Including the lensing magnification will improve the line flux sensitivity by a factor of μ. The gray curves correspond to the line flux sensitivity of 25 (to avoid overcrowding the plot) individual spectra from a single PA. Combining the spectra from the two GLASS PAs for each object further decreases the noise level by a factor of ﹩\sqrt{2}﹩ at all wavelengths.
