Recovery of strikes for two profiles that differ by 1° over all periods: a unconstrained application of the analytic formula. The black line corresponds to the estimates for the base profile of 20, 30, and 40°. The red line corresponds to the estimates of the perturbed profile of 21, 31, and 41°. b Using the reframed version for windows of one period. The black line corresponds to the estimates for the base profile of 20, 30, and 40°. The red line corresponds to the estimates of the perturbed profile of 21, 31, and 41°. In both cases the dashed lines represents the corresponding true values
