SIE parameters. Error bars represents 1$\sigma$ confidence level on
the parameters inferred from the \textsc{mcmc} optimisation. Values into brackets are not
optimised. This corresponds to models where the number of observational constraints is smaller than the
number of free parameters characterising the SIE profile. The goodness of the fit is quantified by the
RMS in the image plane and the reduced~$\chi^2$.
$e$ is the ellipticity of the mass distribution (in units $(a^2-b^2)/(a^2+b^2)$).}}
