Detailed Description

Lazily builds reconstructed missing pt.

Starts from raw missing pt. Type 1 correction, i.e. changes caused by corrections applied to other objects, such as jets, can be included using method PullCalibration. Variations in "unclustered" momentum are applied if requested via the syst option.

If the master configuration contains field fix_ee_2017 in section ptmiss and it is set to true, applies the EE noise mitigation.

Member Function Documentation

void PtMissBuilder::PullCalibration

(

std::initializer_list< CollectionBuilderBase const * >

builders

)

Requests that changes in the total momentum produced by the given builders are propagated into missing pt.

For example, changes in jet momenta due to variations in their corrections can be included this way. If this method is called multiple times, new builders are added to the list of already registered builders.

Used when applyEeNoiseMitigation_ is set.
