Posterior predictive distribution in stellar mass, halo mass, halo concentration, IMF mismatch parameter, half-light radius, and Sérsic index of CMASS galaxies, CMASS strong lenses and SuGOHI lenses, obtained from our inference based on the “Arctan” model. Observed values in , R_e, and n of the 23 lenses in our sample are also shown. Contour levels correspond to the 68% and 95% enclosed fraction.
