Experimental characterization of the QACITS model from on-sky data. Left and right plots correspond to the differential intensity measurements as a function of tip-tilt for the x and y directions, respectively. In both cases, the differential intensity was computed in the inner (blue crosses) and outer (red pluses) areas of the image. The best fit models in the least-squares sense are shown in solid lines (see Eq. (2)for their definition), and the residuals are shown in the plots below.
