Description
As noted in DM-9535, the method used to compute second derivatives in the Brighter-Fatter correction implementation can lead to significant (up to 1%, which is particularly significant for weak lensing considerations) differences in the trace radii of sources, with the differences becoming larger with brighter magnitudes (see figures in DM-9535). This ticket is to investigate the optimal algorithm to use for the Brighter-Fatter correction.
