Analytic Calibration for Perturbation Estimation from Galaxy Images.

This framework is devised to measure the responses for shape estimators that
have been developed or are anticipated to be created in the future. We intend to
develop a suite of analytical shear estimators capable of inferring shear with
subpercent accuracy, all while maintaining minimal computational time. The
currently supported analytic shear estimators are:
+ [FPFS](https://github.com/mr-superonion/FPFS): A fixed moments method based
  on shapelets including analytic correction for selection, detection and noise
  bias. (see [ref1](https://ui.adsabs.harvard.edu/abs/2018MNRAS.481.4445L/abstract),
  [ref2](https://ui.adsabs.harvard.edu/abs/2021arXiv211001214L/abstract) and
  [ref3](https://ui.adsabs.harvard.edu/abs/2022arXiv220810522L/abstract).)
