      Description

      The photometry model may be nonlinear enough that we cannot trivially update the Hessian after outlier rejection, but we may have to recompute it each step. This should be relatively fast for photometry. We can add an option that skips the chol.update() step in FitterBase::minimize(), and make that configurable at the python level, to test whether this improves the fitting stability.
