I'm not sure if JANA/GlueX software still uses this mode of operating. All of this worked at the time with the DKinFit object which existed in the main trunk. You may want to look at test_pKsKs_misspi. That reaction is gamma p --> p KS KS, where the one of the pi- from the KS is missing, but both KS mass constraints are applied.
