Coordinates are given in arcseconds with respect to the cD Galaxy. The ellipticity~$e$ is the one of the mass distribution, expressed as $a^2$--$b^2/a^2+b^2$. Error bars correspond to~1$\sigma$ confidence level as inferred from the \textsc{mcmc} optimization. When the posterior probability
distribution is not Gaussian, we report the mode and asymmetric error bars.
Values into brackets are not optimized. Note that the meaning of the scale radius reported here is different for the generalized NFW~clump and the other mass clumps, described using a dPIE profile with no core.
