class epsf.epsf.EPSF(epsf, true_size=11, oversampling=4)[source]#

Effective point spread function

Python object to store an empirical PSF function. Once created, the Python object can be called to generate a PSF with the desired offset in pixels.

Parameters:

  • epsf (ndarray) – Array with the (oversampled) epsf pixel values

  • true_size (int) – Size (in pixels) of the output images from the epsf.

  • oversampling (int) – Oversampling factor between the epsf pixel and the detector pixels.
