Tip-tilt scanning sequences carried out for characterizing the QACITS estimator behavior. Left: true tip-tilt values as monitored by the secondary component of the binary system, for the scanning sequences along the x (green crosses) and y (blue squares) axes. Right: comparison of the simulated peak transmission curve (flux integrated on a disk of diameter 1 λ/DL) with the experimental results measured from the on-sky data. The effective IWA is reached at a separation of 1.4 λ/DL = 125 mas (computed from the simulated curve).
