Detailed Description

======= DDPlanarDigiProcessor ==========
Creates TrackerHits from SimTrackerHits, smearing them according to the input parameters.

The positions of "digitized" TrackerHits are obtained by gaussian smearing positions of SimTrackerHits perpendicular and along the ladder according to the specified point resolutions. The geometry of the surface is retreived from DDRec::Surface associated to the hit via cellID.

Input collections and prerequisites

Processor requires a collection of SimTrackerHits

Output

Processor produces collection of smeared TrackerHits

Parameters

SimTrackHitCollectionName	The name of input collection of SimTrackerHits (default name VXDCollection)
TrackerHitCollectionName	The name of output collection of smeared TrackerHits (default name VTXTrackerHits)
ResolutionU	resolution in direction of u (in mm) (default value 0.004)
ResolutionV	Resolution in direction of v (in mm) (default value 0.004)
IsStrip	whether the hits are 1 dimensional strip measurements (default value false)
Ladder_Number_encoded_in_cellID	ladder number has been encoded in the cellID (default value false)
Sub_Detector_ID	ID of Sub-Detector using UTIL/ILDConf.h from lcio (default value lcio::ILDDetID::VXD)
