keyword=lots of elasticsThe middle left histogram shows the strength of the elastic peak relative to the N-->Delta transition. In the collimator plot from the previous hclog entry these "clean" elastic protons show up as a hot spot due to two-body kinematics and the hms-sos coincidence. We won't have any trouble getting rid of these clean elastics. The issue will be the "dirty" ones that hit the pipe exiting the spectrometer or which go thru the collimator and have their delta,xp,yp,ytar reconstruction screwed up. Or the radiative tail.
