Raw data – halld_recon
- Raw data is taken in EVIO file format and processed using programs in halld_recon.
- Calibration databases are RCDB and CCDB.
- hd_root is used with plugins for event reconstruction, monitoring and to make REST files
- REST files are in HDDM format (physics quantities, no detector hit information). (Richard)
Simulated data - halld_sim
- Simulated data are in HDDM format. (Richard)
- Event generators generates simulated physics data (particle, momentum, track angle) (Simon & Malte)
- hdgeant4 models the measurements (detector hits) produced by those tracks (Richard)
- mcsmear models the detector resolution which makes the measurements less exact. (Richard)
- MCWrapper runs the above on demand. (Naomi or Sean)
Reaction channel analysis
- ReactionFilter plugin is used to find the events corresponding to a particular reaction to make Analysis Trees. (Beni)
- Requests for analysis trees are bundled together into launches, to generates the trees together. (Alex A)
Analysis Tree analysis
- DSelectors are used to apply filters to the data and generate histograms of invariant mass etc. (Beni)
- FSRoot is an alternative to DSelectors and generates flat trees. (ask Ryan)
- AmpTools is used for partial wave analysis (Malte)
