Notes. In the case of total and tangential magnifications, columns (2) and (3), the uncertainties are given only for the main regions (D1, T1 and UT1); the same uncertainties are valid in all the sub-structures for each of them. The effective radius measured in F115W is reported in Column (4). The β_UV slopes in column (5) are measured using the SW filters F115W, F150W and F200W. Column (6) report the absolute UV magnitudes (derived from photometry in F115W), while the relative SFR_UV values obtained using the relation from Kennicutt & Evans (2012) are given in column (7). The same relation is used to convert the F444W flux (continuum-subtracted using F410M) into a Hα SFR in column (8). The main physical properties derived from the broad-band SED fit (present-age SFRs, mass-weighted ages, masses and extinctions) are listed in columns (9), (10), (11) and (12). All magnitudes, size, mass and SFR measurements (columns 4, 6, 7, 8, 9 and 11) are given already de-lensed, (i.e., as intrinsic values). The best-fit age of D1_core is $12_{- 1}^{+ 0} Myr$ $\rm 12^{+0}_{-1}~Myr$ ; however in Sect. 5.1 we discuss an alternative possibility invoking younger ages. ^†The uncertinaites on SFR_UV are all ≤ 0.01 M_⊙ yr⁻¹ and therefore they have not been reported in the table.
