Pointing jitter model
Implementing a new model that simulates the effect of (spacecraft-induced) pointing jitter/drift on the PSF.
-
First simple implementation could be a simple convolution of existing PSF with gaussian with for width the jitter noise. Using jitter function in poppy to apply jitter during: https://poppy-optics.readthedocs.io/en/latest/api/poppy.Instrument.html#poppy.Instrument -
In a second step, one could input a time series representing the spacecraft jitter, and actually slight change correspondingly the pointing wrt the scene this could be used in combination with the observation mode, a new pointing would then be generated according to a distribution or the exact time series.
