// Class for HF corrections as a function of many variables
// 6 Steps introduced: MC, MC Acc, Reco, Reco Acc, Reco Acc + ITS Cl,
// Reco Acc + ITS Cl + PPR cuts
-// 12 variables used: pt, y, cosThetaStar, ptPi, ptK, ct,
-// dca, d0Pi, d0K, d0Pixd0K, cosPointingAngle, phi
+// 13 variables used: pt, y, cosThetaStar, ptPi, ptK, ct,
