Sensitivity at 1σ in direct coronagraphic images (black lines) and in speckle-subtracted images (colored lines) as a function of time from 0 to 90 min. The profiles are obtained from simulated coronagraphic images based on the 2017-03-25 b original sequence of OPD maps (left) and on the turbulence-subtracted sequence (right). The red curve corresponds to the average sensitivity in coronagraphic images over the full duration of the sequence.
