Smear contamination correction. Top-left: an example CHEOPS exposure where the smear contamination from 53 Cnc, located outside the subarray image, is visible at the left of 55 Cnc (the star at the center of the field of view). Top-right: the same frame after the DRP v12 smear correction. Bottom: the estimated smear contamination flux within the DEFAULT aperture as a function of the observation roll angle which affects each orbit.
