Corner plots of the parameter space (α, log M_c) (the slope and the cut-off mass, respectively), obtained fitting a Schechter mass function (Eq. (8)) to the Hα and UV tail (top row) and extraplanar (bottom row) clump mass distribution. The values at the top of the histograms are the median of each distribution for the corresponding parameter, with uncertainties given by the 84th percentile minus the median and the median minus the 16th percentile (upper and lower uncertainty, respectively). The same values are also reported as black dashed vertical lines in the histograms.
