Technical description :
In the paper we explain procedures designed to measure the position angle, the ellipticity and the half-light radius of lensing galaxies, that rely on an innovative scheme to compute isophotes. Table 6 details frame per frame the characteristics of the masks used in this work. Those values are in fact the shape parameters of the galaxies,
before correcting from the effect of the PSF. The relative coordinates of the galaxy center, with regards to a reference lensed image, and the size of the region of interest are given as well. The reference lensed image can be found in Fig. 2 in the paper and is the one labelled A (or A1 in some cases).
