Notes. Summary of the considered strong lensing models and their global results. Columns show the model IDs, the number of degrees of freedom (d.of), the number of input images used, the best fit positional Δrms (see Eq. (5)), the value of the reference 
(computed considering an image positional error of 
, see Eq. (4)) and a short description of each model.
