Stellar mass ${\chi }_{\nu }^2$-weighted probability densities of all CIGALE models (black line). Each panel represents the modeling of an individual BB. The distribution modes and CIs are shown with vertical dashed and dotted red lines, respectively. The logarithm of the estimated M_⋆ is shown at the top of each panel with red fonts. The blue error bars represent the bin modes and CIs of the model’s ${\chi }_{\nu }^2$ at the plotted M_⋆ range divided into 12 bins, while the right y-axis corresponds to the ${\chi }_{\nu }^2$ values.
