Ringing effects reduction by improved deconvolution algorithmApplication to A370 CFHT image of gravitational arcs

Roche, Muriel Bracco, Christian Aime, Claude

We develop a self-consistent automatic procedure to restore informations from astronomical observations. It relies on both a new deconvolution algorithm called LBCA (Lower Bound Constraint Algorithm) and the use of the Wiener filter. In order to explore its scientific potential for strong and weak gravitational lensing, we process a CFHT image...
