2 : // Class for handling of ESD track cuts.
3 : //
4 : // The class manages a number of track quality cuts, a
5 : // track-to-vertex cut and a number of kinematic cuts. Two methods
6 : // can be used to figure out if an ESD track survives the cuts:
7 : // AcceptTrack which takes a single AliESDtrack as argument and
8 : // returns kTRUE/kFALSE or GetAcceptedTracks which takes an AliESDEvent
9 : // object and returns an TObjArray (of AliESDtracks) with the tracks
10 : // in the ESD that survived the cuts.
11 : //
12 : //
13 : // TODO:
14 : // - add functionality to save and load cuts
15 : // - add histograms for kinematic cut variables?
16 : // - upper and lower cuts for all (non-boolean) cuts
17 : // - update print method
18 : // - put comments to each variable
