Observable

Description

Represents an observable that can be unfolded

Idea:

• use pointers to this abstract class to define observables in daughter classes
• this class handles everything that doesn't access event data (e.g. the binning)
• it also gives access to a Filler through getFiller()

This class is used repeatedly by several executables related to the unfolding (nearly all, to the notable exception of unfold itself), as well as in macros used for plotting.

Member Function Documentation

getFiller()

unique_ptr< Filler > getFiller ( TTreeReader &  reader ) const

virtual

Constructs a filler for the observable. By default, a dummy filler is returned.

Reimplemented in HTn, ZPtY, MjjYmax, MjjYbYs, PtY, DEtaDPhi, and BF.

{
    cerr << orange << "Warning: the default `Filler' does nothing\n" << def;
    return make_unique<Filler>();
}

getTransformer()

unique_ptr< Transformer > getTransformer ( TUnfoldBinning *  bng ) const

virtual

Constructs a filler for the observable. By default, no operation is applied.

Reimplemented in HTn.

{
    return make_unique<Transformer>(bng);
}

setLmatrix()

void setLmatrix ( const std::unique_ptr< TH1 > &  , std::unique_ptr< TH2 > &    )

virtual

Construct regularisation matrix.

Reimplemented in HTn, ZPtY, MjjYmax, MjjYbYs, PtY, DEtaDPhi, and BF.

{
    cerr << orange << "Warning: the default L-matrix is empty\n" << def;
}
