  \caption{\label{fifthtable}Properties of the fifth images on real data (R.) and
    predicted from the best lens modeling (IS or NFW). The positions
    $(x,y)$ are given in arcsec, with respect to the cD centroid.
    Position angles (PA) are given in degrees and $a/b$ is the axis ratio.
    The errors are found from the changes when varying some {\tt SExtractor}
    parameters.
    Although both the position angles and the ellipticity of the IS
    and NFW are compatible with the data, there is a significant difference
    in positions. The offset $\vert\delta\vec{x}\vert$ between the IS and
    the real position is only~$0.16\arcsec$, whereas it is~$0.36\arcsec$
    for NFW, which is larger than uncertainties on observations
    (third column $\vert\delta \vec{x}\vert \sim 0.05\arcsec$).}
