AO response to two OPD gradients localized along different spiders with 500 nm OPD ptv each. The OPD has a discontinuity at the position of the spider, and decreases exponentially with the distance to the spider. There is no atmosphere. The SR at H-band for the perturbation before closing the AO loop is 94% (a). The SR at AO convergence is 55% (b).
