Probability density of predicted time-delay for image pair AE of the sextuply lensed quasar. Shown are the delay predictions for the various power-law models (dotted salmon colored) according to their corresponding BIC weight. Also plotted are the delay predictions for the fiducial power-law model (solid red) and the fiducial composite model (solid blue). The thick black solid line represents the combined probability density of all BIC weighted models. The factor λ represents the presently unknown external convergence and the MST factor, to be determined with ancillary data.
