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.

B2KKKS Homemade Fit
1. Fits without any additional cuts respect to the ANAnote, i.e., here PROBNNp > 0.9

LL-SecondaryPeak
Let's compare the ANAnote yields with those from our homemade fits.
Homemade fit:
ANAnote fit:
