Caption: Figure 6.

On-sky measured corrected PSFs (top row) obtained with modal on-sky CACOFONI (left), and a synthetic matrix. The corresponding measured Strehl ratios are 40.0% and 38.1%. The intrinsic seeing variations during the sequence are likely larger than the difference in performance between the different control matrices.
