Notes. (#)The magnification value of the least magnified multiple image. ( ⋆ )Flux or angular separation ratios are indicated with “F” or “A”, respectively, and are calculated on images with IDs reported in Cols. 1 and 3. (I)The flux ratio calculated among images 1a (the least magnified) and 1c (the most magnified), based on the F814W band. We note that μtot(1a) is possibly subjected to large uncertainty, we rely on the lens model for the magnification of this object (see Appendix E). (II)Ratio of the angular separations between knots 5.4 and 5.2 for group images “a” and “c”. (III)Based on flux ratio between images 14.2b (or 14.1b), and the least magnified image 14f, taking into account that 14f is the sum of the two knots (14.1+14.2, see Sect. 6.2). (IV)Based on the relative angular separation among knots 14.2b−14.1b and the upper limit on 14.1f (see Appendix C).
