  12. rpc/PS_pion/PS_summary.kumac No calibration whatsoever Calibration with muon response

  13. Fits

  14. rpc/PS_pion/PS_summary_alpha.kumac runs calib_1.f Calibration study α=0.4 This is interesting. It appears that a linear calibration does not work as well as a calibration attenuated by a power…
