PSF-SIM. New PSF field variations.

[tobias-liaudat]

Generate the new PSF field variations that were proposed by PA.F. Briefly, the Zernike polynomials coefficient array should maintain a constant WFE_RMS throughout the FoV.

So, the norm of the Zernike coefficient array should remain constant (belong to a scaled hypersphere) and the values of the array should change (smoothly at first) thought the FoV (angular variations of the array).

Besides this we need a simple coefficient matrix for a polynomial variation of the OPDs on the PSF field.

We need to save the PSF field coefficient matrix! Why? To compare it to the matrix we are recovering with the parametric model.

• [x] Modify the PSF-field generator so that it resembles the parametric PSF model.
• [x] Generate a new dataset with the coefficient matrix.

Done!
