Examples of robust halo removal on (130) Elektra with different instruments (see also Fig. C.1). First (resp. second) column - blurred data, d (resp. deconvolved image, o, and halo model, d^mod = p ★ o), normalised and displayed with a dual linear scale. Third column - deconvolved PSF, p (peak normalised to one). Fourth column - residuals of the halo model, d − d^mod. Fifth column - map of the equivalent robust weights, $w^{\rho }(\sqrt{\mathit{w}}(\mathit{d}-{\mathit{d}}^{\text{mod}}))$. Orange arrows: camera defects, dead pixel clusters, or cosmic rays. When visible, the three moons of (130) Elektra are circled. The red arrows point towards the outer moon when it is outside the FoV. Last line – examples of PSF on a star for each instrument.
