Inferred density of the luminosity segregated models. The data are binned in three bins of the J band: J < 12, 12 ≲ J ≲ 15, and 15 < J (with colours green, cyan and magenta, respectively). The MAP is shown by means of three coloured solid lines, the colours correspond to those of the J band bins. In these MAPs, the core radius is increased accordingly to Eq. (13) using the mean value of the J band in each bin. Also shown are 100 samples from the posterior distribution (grey lines).
