Draft: Rich: implementation of matching rings to mcTracks for multiple MC input files
This MR allows to match rings to MCTracks if multiple MC input files are provided, e.g. urqmd and beam background.
Might be of interest for @f.kornas @v.friese .
In draft mode, since there are some todo's:
-
In 6 places the 'vector<pair<Int_t, Int_t>>GetMcTrackMotherIdsForRichHit' implementation is used, which will not work after this MR anymore.
- [ ] Remove the 'vector<Int_t>' and 'vector<pair<Int_t, Int_t>>GetMcTrackMotherIdsForRichHit' functions
The CbmRichRingFinderIdeal
is disabled with this MR and will be properly implemented in a future MR.
Hits from the same mother particle in different RICH cameras will then be properly taken into account for the CBM RICH.
