      Description

      Pupil illumination is the same at different levels of defocus, and only the wavefront changes. At the moment, I do iterative estimate which fits each spot at each defocus separately. This sometimes produces a consistent estimate of the illumination, but sometimes not. In particular, FRD estimate is often discrepant at different levels of defocus. Example.png shows an example of two spots. In the upper row, the estimate is inconsistent at two sides of defocus (frd_s values are very different). In the lower row, example where they are consistent. The estimation code should handle this properly, by analyzing images at the same time.
