ePSF

The task of the ePSF blocks is to build and model the effective PSF on an Image.

ePSF building blocks

The following blocks can be used to build an effective PSF from a set of stars. Once an effective PSF constructed, it is stored as an Image in Image.epsf.

MedianEPSF

Stack cutouts into Image.epsf: a median effective PSF
