\caption{Relative astrometry, flux ratio (with respect to image~A) and absolute  photometry in filters~$F555W$, $F814W$ and~$F160W$ of the lensed QSO~images~A, B, C, D, as derived from PSF~fitting (see Sect.~\ref{sec:fit2}). After the Einstein ring has been subtracted, relative astrometry and absolute photometry are derived  for the lensing galaxy~G from the best fit of the S\'ersic~model (see Sect.~\ref{sec:fit4}). After subtracting the lens, the astrometry of component~$X$ is derived from a~Gaussian fitting and its magnitude from aperture photometry (corrected for infinite aperture). Theoretical magnification ratios~$M_{\rm A}/M_{i}$ and the (unobserved) AGN~position are derived from our fiducial lens model (see Sect.~\ref{sec:fit5}). Magnitudes of the host are calculated in Sect.~\ref{sec:fit6}.   Quoted errors are standard errors on the mean, computed from the results on the NExp~individual frames, including the systematics estimated in Sects.~\ref{sec:red} and~\ref{sec:photcal}.  Boldface indicates the final, weighed average astrometry derived from all bands.}
