16 | // Class AliHFEtaggedTrackAnalysis | |
17 | // Analyses tracks with an apriori PID information (i.e. using the daugther | |
18 | // tracks from well-identified decays of neutral charged particles). Tracks | |
19 | // are processed in the Process function, where given tracks are filtered | |
20 | // via the track cuts and used for PID later. The plugin fills Correction | |
21 | // Framework containers and additional PID QA containers | |
