Resulting corner plots from fitting the M21 model to mock data generated with SSU (see Sect. 4.1 for a detailed description). The orange contours and histograms correspond to the scenario where the subhalos are considered ("with subs"), while the green color represents the case when subhalos are excluded ("no subs"). The intrinsic parameter values for the "with subs" and "no subs" cases are illustrated by the dotted dashed orange line and the dashed green line, respectively. Above each histogram, the best-fit value is displayed in the corresponding color, while the intrinsic value is shown in parentheses and in black. Note that the intrinsic values of the shot noise in the "no subs" and "with subs" case are not the same.
