AnaCal

Analytic Calibration for Perturbation Estimation from Galaxy Images.

This framework is devised to bridge various analytic shear 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: A fixed moments method based on shapelets including analytic correction for selection, detection and noise bias. (see ref1, ref2 and ref3.)
