Check PID cuts
- proton PID variables (PROBNNp) for Run I KK seem to have a cut already applied.
- See here the comparison between efficiencies after a cut PROBNNp < 0.9 and :
- This came up when we were calculating efficiencies in order to have a rough estimate of the impact of these cuts in the fit yields.
