On-sky optimization map on subaperture associated with the MEMS segment number 16, with an integration time of 2 ms for each of the 81 individual images acquired to derive the map. The tip-tilt range is −2 mrad to +2 mrad on the segment, with a 0.5 mrad step. This corresponds to ±480 mas on-sky, with a step of 106 mas.
