Corner plots for the galaxies Triangulum II (upper panels) and Segue 1 (lower panels), with no PBH effect (f_PBH = 0), and for two different IMFs: the BPL (left panels) and LN (right panels) distributions. The confidence levels, centred on the median, are represented by 1σ, 2σ, and 3σ intervals, with colours ranging from darker to lighter shades. For easier comparison with Reticulum II (see Fig. 4), we show the median values of the parameters inferred for that galaxy as dashed lines.
