Notes. Columns 1 and 2 show the RA, Dec of Tr and its five counterimage candidates. Column 3 lists the magnitudes in the filter F606W (or in the filter F390W and in the Vega system in parenthesis). Columns 4 and 5 show the magnification and time delays predicted by lens model M1, while for model M2 are shown in Cols. 6 and 7. Time delays are expressed in days. Magnification ratios with respect to Tr are shown in Cols. 8 and 9 for models M1 and M2 respectively. Column 10 shows the magnification ratio with respect to Tr estimated from the ratio of distances between the knots 5.1 and 5.2 bracketing the positions of Tr and t1–t5. The last column shows the flux ratio between the observed fluxes and the flux at Tr.
