Basic Description of main classes and use cases

• PROlog : Fairly simple logging/verbosity wrapper class. This is the only way PROfit should print. Usage as:
  • log(L"%1% || Using a total of %2% individual files") % func % num_files;
  • LOG CRITICAL = 0
  • LOG ERROR = 1
  • LOG WARNING = 2
  • LOG INFO = 3 : This should be level of standard physics output that someone would plausibly use, but not create giant log files!
  • LOG DEBUG = 4
• PROconfig : Primary bookkeeping and XML loading class. Stores ALL information of mode-detector-channel-subchannel information. Must be created once and only once per PROfit executable and passed by reference to more complex functions when it is needed.
  • Contains helper functions channel<-> subchannel mapping..etc..
  • As well as functions for how to collapse subchannels to channels
• PROspec : Class for storing final spectra and errors. Barebones class as all binning,collapsing handeld by PRoconfig/
  • Essentially two Eigen::VectorXD ! Simple with helper functions
• PROpeller : The PROpeller, which moves the analysis forward. A class to keep all MC events for oscllation event-by-event.
  • Saved as a set of six std::vector floats or ints.
  • Currently only truth (energy), reco (energy) baseline, pdg, addedweight and precalculated bin incicies indicating where the reco variable fits in a given PROconfig defined binning.
• PROtocall : Currently a bit of a rogue set of functions that, given a PROconfig, dictate how to get binning and collapse Covariance matricies
• PROcess : The master weighting function that combines everything to give one final output spectra (PROspec) event-by-event.
  • FillRecoSpectra (PROconfig,PROpeller,PROsyst,PROosc, shifts, phys param)
• PROcreate : Workhorse classes for loading the set of root ntuples and systematics into PROspec CV class and a vector of SystStructs for systematics.
  • Needs a PROconfig to tell it exactly what to load and where (channel and subchannel info) to assign the variables. Also which systeatics to load.
  • The class SystStruct is also defined in here (for some reason), which stores the weights and spline information for systematics
• PROsyst : Class that groups all systematics (each with a SystStruct) and manages their formation and effect on PROspecs
  • i.e generates covariance matricies, fills splines, gets spline shifted spectrum.. etc..
  • Currently has Spline (CAFana style), Covariance (SBNfit style) and MFA (2D spline to-be-implemented) options
• PROsc : The model class (not the lack of second 'o'). Currently is a very simple hardcoded 3+1 SBL approximation. -- End goal to implement custom classes, NuSquids..etc..
• PROchi : Class that gathers the MC (PROpeller), Systematics (PROsyst) and model (PROsc) and forms a function calculating a chi^2 that can be minimized over
