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

ePSF modeling blocks#

Gaussian2D

Model Image.epsf as a 2D Gaussian profile

Moffat2D

Model Image.epsf as a 2D Moffat profile

JAXGaussian2D

Model Image.epsf as a 2D Gaussian profile (powered by `JAX`_)

JAXMoffat2D

Model Image.epsf as a 2D Moffat profile (powered by `JAX`_)
