Detailed Description

RawDataManager: read raw, MC and reconstruced data files and loop over them

The input for the RawDataManager are directories with raw and, optionally, reconstructed and Monte-Carlo files. It scans for available files, reads them and provides access functions to loop over time frames and events. Supported data files:

  • trdtracklets.root (required): TRD tracklets and trigger records
  • trddigits.root: TRD digits - might only be available for some events
  • o2_tfidinfo.root (reconstructed data only): time frame information
  • o2sim_HitsTRD.root: TRD MC hits with global and TRD chamber coordinates

The following file types had some support in previous private branches, but need further cleanup before integration into O2:

  • o2match_itstpc.root: ITS-TPC tracks
  • tpctracks.root: TPC-only tracks
