Posterior of the key lens model parameters for the lensing and time-delay data. Each color represents a particular source resolution that is the dominant systematic uncertainty in the modeling of the ACS data. The solid curves are a Gaussian fit to the PDF by weighting each source resolution chain equally. The contours/shades mark the 68.3%, 95.4%, and 99.7% credible regions.
