keyword=Pion-Kaon IdThe figure below shows the deltap distribution for kaon vs pion selected tracks.
Kaon selection is L.a1.asum_c<10&&L.a2.asum_c>150&&L.a2.asum_c<1200
Pion selection is L.a1.asum_c>10&&L.a2.asum_c>50
The figure shows that at very high deltap Aero1 is probably inefficient such that a Pion is misidentified as a kaon.
At the same time at very high deltap there is a "deficit in identified pions"
So, it is safe to analyze data with a cut abs(deltapL,R)<0.04
