- Range vs Energy with all the other cuts applied except for
the range-momentum cut (dashed lines are for the extended box), the
red colour dots are for the kmu2 events with the TD cut inverted, the
blue colour dots are for the kpi2 event with the photon veto inverted.
The number of the events inside the box indicates the background level if
the corresponding rejection is applied. eps gif jpg

for the range-momentum cut (dashed lines are for the extended box),
the red colour dots are for the kmu2 events with the TD cut inverted,

- The pion/muon separation from the range-momentum measurement
(when momentum reaching to 229 MeV/c, the Kmu2 tail starts to
contribute. As a result, the power of separation decreases) eps jpg
- The pion/muon separation from the RS dE/dx measurement (when
momentum approaching to 225, the sample contains more kmu2 tail events
involved the scattering effect, which gives a bad energy measurement
in the Range Stack and resulting in a worse dE/dx measurement. Therefore,
the dE/dx can have more rejection to it.) eps
