\caption{\label{tab:res}{\it Left}: relative positions between the different lensed 
components (B, C, D) and the lensing galaxy (G) with respect to
component A as deducted from the best seeing EFOSC-2 frame using the
GENERAL (GEN) and MCS~codes (see text). {\it Right}: relative
magnitude of the~B, C, D lensed images with respect to~A deducted with
the MCS method at two different epochs. The last two columns give
respectively the amplification $\mu_{\textrm{\tiny{exp}}}$ (sign~=~parity) predicted by the SIS$+\gamma$ model and the corresponding
relative magnitude with respect to~A (Sect.~\ref{sec:mod}).}
