Examples of different perturbations introduced on DM1 (top) and their corresponding LOWFC loop responses on DM1 (bottom), obtained by projecting the command on the controlled basis of the LOWFC loop and using the control matrix to estimate the feedback command. From left to right: the Zernike mode Z₄ used for the interaction matrix calibration, a single update from SM after convergence of the DH digging, and a command update from the LOWFC loop to correct for residual turbulence in closed loop. In the bottom row, all the displayed commands are scaled to fit the same color bar. From left to right, the commands have been multiplied by 1, 5268 and 339 respectively to be displayed with the same color bar, and the respectively applied amplification factor is displayed on top of each command. The commands shown here expand over the whole controllable area of DM1. The hexagons represent the projection of the segmented aperture onto DM1.
