Notes. Marginal 68% confidence intervals on single parameters are taken from the extremes of the Δ S = 1 contours. The 68% confidence intervals on the luminosity density and SFRD however depend on the joint confidence interval the two free parameters L and α (Δ S = 2.30 contour as in Fig. 8) – details in Sect. 5.3. We note that as our sample are almost entirely below L, the value of L itself is only loosely constrained by our data, and hence we only find a single bound of the 68% confidence intervals for the Schechter parameters in two redshift bins. Thankfully this is not a problem for the luminosity density and SFRD, as the extreme values are reached in a perpendicular direction to the length of the ellipses.


>25% completeness in flux at the median redshift of the luminosity function.


Integrated to log10L erg s-1= 41.0.
