Xic2LambdaKPi patch

Marian Stahl requested to merge mstahl_Xic2LambdaKPi_patch into run2-patches

Update of config for Xic2LambdaKPi module after validation and lessons learned from 2017 re-stripping

  • Likely misuse of D2DVVDCHI2SIGN functor. EDIT: seems to be OK. Functor is same as FDCHI2_ORIVX from TupleToolGeometry
  • Learned from 2017 re-stripping that the current selection is suboptimal. Especially the BPVVDCHI2>24 cut kills roughly 50% of the \Xi_c^0 signal
  • I assume that the StrippingXic2LambdaKPi_XiczLine has a large correlation with the new Hc2V02H_Xic2LambdaKPi line (!1325 (merged)) on the same stream. I hope this is no problem. For 2017, there is a dedicated \Xi_c^0\to\Sigma^0 K^- \pi^+ line that allowed us to remove StrippingXic2LambdaKPi_XiczLine. This is not the case here, therefore I would like to keep the line.
