Coronagraphic focal plane images showing the wind-driven halo. Left: simulation of a perfect post-AO coronagraphic image of infinite exposure using an analytic AO tool (accounting only for fitting and servolag errors). Right: one exposure obtained with SPHERE-IRDIS (H2 band). Both images are in logarithmic scale to emphasize the WDH. The two regions encircled with yellow dotted lines are artifacts caused by the manufacturing technique of the DM.
