Top: MCMC post-burn distribution for the seven free parameter of the fiducial model. The histograms show their marginalized PDF, and the vertical blue lines show their best-fit value and their 1-σ error. The scatter plots show the two-dimensional PDF for the parameters colored by log-likelihood, with yellow colors indicating higher values. The red-dashed lines indicate each parameter’s best-fit value (median) location, and the black-dashed contours show their 1-σ and 2-σ error. Bottom: plots show the one and two-dimensional PDF distribution for M_vir, M_* and c_vir. Lines and contours in this plot are the same as in the left panel, but all are shown here in black.
