(

const std::string &

name

)

Constructor.

Parameters

name	The name of the algorithm

Member Function Documentation

BuildAxis()

bool Herd::TimingCaloAxisTrackingAlgo::BuildAxis ( const CaloHits &  caloHits, std::string &  hitsObjName, size_t  clusterIndex  )

private

Build Shower Axis.

Combine the position of the entrance tile in PSD with the distribution of the CALO shower to reconstruct the shower axis
