Fix Version/s: None
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.

Bob Armstrong, do you have time to review this?
Thanks Bob Armstrong. I ran every combination of Jenkins and it passed all it currently can, i.e. through ci_hsc on all py2 os' (centos6&7 and OS X), but only lsst_distrib on py3 (since ci_hsc hasn't been py3'd yet).
Bob Armstrong — Lauren MacArthur suggests that we assign this ticket to her, since she already has a fix on that branch, and have you act as reviewer. If you object, do shout!
