M₁₅₀₀ and SFR_UV vs. UV slope. The sample selected as LBG-only is shown in grey, and the LAE+LBG sample is colour-coded by redshift. Binned averages in SFR_UV for the LBG and LAE+LBG samples are shown with red circles and golden squares, respectively. Each bin contains an equal number of the respective samples, and the horizontal error bars show the width (in terms of β) of each bin. Errors on the LBG-only objects are omitted for readability, and we note that there are LBG-only objects (and four LAE+LBG objects; see Fig. 5) that extend beyond the β limits of this graph; however, they are objects for which the calculation of the UV slope is uncertain. There are LBG-only objects that extend beyond the M₁₅₀₀ limits of the graph, but these are taken into account when computing the binned averages.
