2 | * This macro estimates efficiency of matching with the TOF. * | |
3 | * TOF "Good" tracks are those originating from the primary vertex, * | |
4 | * being "good" in the ITS and having at least one digit in the TOF. * | |
5 | * (To get the list of "good" tracks one should first run * | |
6 | * AliTPCComparison.C and AliITSComparisonV2.C macros) * | |
7 | * Origin: I.Belikov, CERN, Jouri.Belikov@cern.ch * | |
