Power-law slope, Einstein radii for both deflectors, P0 (main deflector) and P1, and predicted time delays for the two mass profile assumptions of the main deflector. The power-law and composite model results are shown in colors red and blue, respectively. In the composite model case, the Einstein radius of the main deflector, P0, is calculated via the circularized average of the convergence and the power-law slope represents the derivative of the convergence at the Einstein radius. To address computational challenges in sampling the composite model parameter space, the mass of deflector P1 is held fixed at the power-law model results, and therefore no composite model posteriors are shown.
