PSF

Definition of the PSF

  • The PSF must be describe separately to the source shape.
  • convolution of the source shape and the PSF.
  • done in case of gaussian model for both source and PSF but in python code, should be moved in c code

PSF model

Double Gaussian model

Done but in python code, should be moved in c code.

TODO

  • PSF scale factor as function of wavelength

factor = polynomial function of wavelength

For double gaussian model, we should define one function for each gaussian component.

  • PSF scale factor as function of FoV

Idem but depending on the detector coordinates.

  • New models

To be define

PSF image

TODO:

  • able PSF definition with an image (aXeSIM ok)
  • able subsampled PSF
  • PSF data cube (several images at different wavelength and interpolation)
  • See Martin's notes
