Add jitter to ParametricPSFfromPSD
The jitter is a convolution (by a gaussian function) in the PSF domain, it could be easily implemented as a multiplication (by a gaussian function) in the OTF domain. It might help to match the drop of OTF around the telescope cutoff frequency.
Concrètement, dans ParametricPSFfromPSD._otf
on aurait la multiplication des quatre OTF suivantes:
- turbulente (à partir de la PSD de phase)
- diffraction
- décalage en pixel
- jitter
