Instruction

Special Proposals

Parameter flipping or circular bounds are no longer hardcoded — they are now set via the configuration file.
Users must modify the config to specify, for example:

- Systematic:
    Names:
      FancyName: delta_cp

    SpecialProposal:
        CircularBounds: [-3.141592, 3.141592]

or

- Systematic:
    Names:
      FancyName: delm2_23

    SpecialProposal:
        FlipParameter: 0.

This is important — otherwise, the code will not reproduce previous results, even though it may appear to run without errors.

Oscillation Parameters

Oscillation parameters are no longer in a separate class but now are part of ParamterHandlerGenreic. This only requires passing the oscillation model YAML config with the remaining yaml configs.

Previously oscillation parameters had some global step scale. While in full/merged object global step scale will be different. Therefore we recommend tuning individual step scales for osc params.

Return Parameter Binning

Previously, this was a pure virtual function. Now, the entire functionality is handled within SampleHandlerFD.
Binning is now specified via the configuration file.
First, in your sample config, add the entry:

BinningFile: "Configs/Samples/Binning.yaml"

This binning.yaml can have the following form:

TrueNeutrinoEnergy: [0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5,
                      5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5]
RecoNeutrinoEnergy: [0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5,
                      5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5]

Instruction

To introduce a more flexible structure that allows for future improvements (such as storing multiple samples in one object), it was decided to remove the so-called Oscillation Loop structure.

Old Code

for (unsigned int iSample = 0; iSample < MCSamples.size(); iSample++) {
    for (int iEvent = 0; iEvent < MCSamples[iSample].nEvents; iEvent++) {
        MCSamples[iSample].xsec_w[iEvent] = 0.;
    }
}

New Code

for (int iEvent = 0; iEvent < MCSamples[iSample].nEvents; iEvent++) {
    MCSamples.xsec_w[iEvent] = 0.;
}

Memory Structure Impact

This change exacerbated an already inefficient memory layout. FarDetectorCoreInfo, which MCSamples is based on, stores multiple vectors. Accessing elements from these vectors leads to large memory jumps—especially after removing the oscillation channel.

Event Class

To address this, the FarDetectorCoreInfo structure was updated to store single-event values rather than vectors. As a result, most of the codebase now uses:

MCSamples[iEvent].xsec_w = 0.;

instead of:

MCSamples.xsec_w[iEvent] = 0.;

Implication for Plotting Variables

This change makes storing additional variables for plotting more problematic. Therefore, we recommend that experiment-specific plotting variables either:
• Be stored in a separate object, or
• Be conditionally compiled using #ifdef.

Example

Separate object solution could look like:

/// header file
std::vector<ExpEventInfo> ExpEvent;
std::vector<ExpAdditionalEventInfo> ExpAddEvent;

and then you

double SampleHandlerExp::ReturnKinematicParameter(KinematicTypes KinPar, int iEvent) {
  double Val;
  KinematicTypes Var = static_cast<KinematicTypes>(KinVar);
  switch(Var) {
  case kFittTimeVariable:
    Val = (ExpEvent [i].Variable);
    break;
  case kPlottingVariable:
    Val = (ExpAddEvent [i].AnotherVariable);
    break;
   }
  return Val;
}

CleanMemoryBeforeFit

We introduced a new pure virtual function to SampleHandler.
The main aim to to have a function which deletes all auxiliary event information before fit starts. Which would give control over structures you want to have for plotting but not necessarily during the fit time.
