68% and 95% confidence contours from Monte Carlo error analysis for the best-fit parameters ρ, a, and f_sh, from the case of shear (iii). The central star shows the MLE of the parameters. We emphasize the a vs. ρ plot since there is a fiducial value for a (=2, vertical dotted line), and ρ has constraints set on it by Jorstad et al. (2005) and Pushkarev et al. (2009).
