Description
Huff and Mandelbaum calculate R_psf. One can avoid this step to first order by symmetrizing the psf upon reconvolution. Apparently for a well behaved and well modeled psf, such as that of DECam, this step is unnecessary, but for a more anisotropic psf, such as that of Subaru Suprime cam, this might not be the case. Can the user currently choose between these three options in the code?

Research direction
No file, test, or entry point is named. Start by locating the pipeline's PSF reconstruction and response-handling entry points, then compare the current behavior with the three choices described in the issue. Done means the supported choice is established, or the required user-selectable behavior is clearly specified and covered by tests.
