Convergence of CLOSE gains on the 2.0 s following closing of the AO loop for guide stars of M_R = 0 and 16 and atmospheric r₀ of 14.5 and 9.0 cm. All G_i are initialized to 0.5 at the start (blue line). G_i values are shown as averaged over the time windows given in the legend. Curves are smoothed along the i index for clarity. Final SRs are given in H band and are computed from the cumulative exposure over the last 200 ms (k ∈ [900, 1000]).
