Corner and 1D posterior marginalized distributions for the fitting parameters θ_FDM and M_⋆ in the FDM plus baryons model for the two benchmark galaxies: WLM (top panel) and DDO 154 (bottom panel). Posteriors in the 1D plots show the 16%, 50%,  and 84% CL ranges. The priors are shown in Table 1 and the blue lines and dots indicate the maximum posterior values of the parameters from the MCMC samples. Contours in the 2D plots display the ∼39.3%, 67.5%,  and 86.4% CL regions, corresponding to the 1, 1.5, and 2σ regions of a 2D normal distribution. Cases where an additional inner contour is present denote an ∼11.8% CL or 0.5σ region.
