As Fig. 6, using the mean column density for all of the absorbers (top panel), only the Mgii absorbers normalised by with the DLAs normalised by the actual N_{H i} measurements (see Curran 2017, middle panel). In these two panels the bin size has been doubled to n = 50 (halving the number of bins), in order to improve the signal-to-noise ratios. The bottom panel shows only the Mg ii absorbers normalised by , where the sample of 188 is binned into four bins of 47. As per Fig. 5, the curves show the SFR density arbitrarily shifted on the ordinate, where the same shift is used in each panel.
