Metacalibration and shape measurement by automatic differentiation
Project led by @andrevitorelli
This project relies on jax-galsim (which
itself depends on GalSim >=2.8) for
image interpolation, shearing and (de)convolution, and on JAX
for automatic differentiation:
$ pip install jax jaxlib jax-galsim "galsim>=2.8"To run the tests, ngmix is also required, as several tests cross-check autometacal's results against it:
$ pip install ngmix
