Detailed Description

Implements reweighting to account for self-veto due to ECAL L1T prefiring.

The prefiring problem is described here. The reweighting is enabled only when running on simulation and only if the master configuration contains key l1t_prefiring set to true.


Member Function Documentation

virtual int L1TPrefiringWeight::NumVariations (  )  const [inline, override, virtual]

Returns number of supported systematic variations.

Up and down variations are counted separately. The nominal weight is not included.

Reimplemented from WeightBase.

virtual double L1TPrefiringWeight::operator() (  )  const [inline, override, virtual]

Returns the default weight.

This might be different from the nominal weight if a specific variation has been requested via command line options.

Reimplemented from WeightBase.

double L1TPrefiringWeight::RelWeight ( int   )  const [override, virtual]

Returns relative weight for requested systematic variation.

The relative weight is computed with respect to the nominal weight. The argument must satisfy 0 <= variation < NumVariations().

Reimplemented from WeightBase.

std::string_view L1TPrefiringWeight::VariationName ( int   )  const [override, virtual]

Returns the label of the systematic variation with the given index.

If the variation has the meaning of an "up" or "down" one, the label must end with "_up" or "_down" respectively. The argument must satisfy 0 <= variation < NumVariations().

Reimplemented from WeightBase.


Member Data Documentation

TTreeReaderValue<Float_t>* L1TPrefiringWeight::defaultWeight_ [private]

Non-owning pointer to one of the source weights.

Used to provide the default weight by operator(). Only initialized if the reweighting is enabled.
