Range of convergence and shear for the best models. The colored disks show the values of κ and γ for 50 models which are randomly selected among the best likelihoods according to Eq. (4). Different colors are used for each image position. The disks surrounded by the thick black circles correspond to the best model in Table 1. The triangles are the model M3 in Williams & Zegeye (2020), while the diamonds are the model in Mörtsell et al. (2020).
