1σ standard deviation of coronagraph intensity versus the seeing, for a bright case, τ₀ = 2ms, and different pyramid modulation radii: 3, 2, and 1 λ_WFS/D. We compare the performance of the system without correcting the NCPA (blue), correcting the NCPA with the PWFS reference offset but without optical gains (orange), including an optical gain calibration (green), and the performance without NCPA, which we want to retrieve (red).
