Detailed Description

Cluster finding and hit reconstruction algorithms for the TRD(2D) module.

Extend the TRD module reconstructor for the particular case of inner TRD-2D modules. The class is a collection of algorithms to :

  • identify time and spatially correlated digis and build clusters
  • identify the type of clusters and apply further merging/deconvolution
  • apply FEE (channel gain, baseline) and detector (energy gain, maps, etc) calibration
  • steer the calculation of hit 4D parameters (x, y, t, E)
