Detailed Description

======= SimpleDiscDigiProcessor ==========
Produces a TrackerHit collection from SimTrackerHit collection.

The positions of "digitized" TrackerHits are obtained by gaussian smearing positions of SimTrackerHits in (x,y) plane according to the specified point resolution.

Input collections and prerequisites

Processor requires collections of SimTrackerHits

Output

Processor produces collection of smeared TrackerHits

Parameters

CollectionName	The name of input collection of the SimTrackerHits (default name FTDCollection)
OutputCollectionName	The name of output collection of TrackerHits (default name FTDTrackerHits)
PointResolution	Point resolution in (x,y) for the planar detectors (in mm) (default value 0.01)
Sub_Detector_ID	ID of Sub-Detector using UTIL/ILDConf.h from lcio (default value lcio::ILDDetID::FTD)
keepHitsFromDeltas	Whether to include hits from secondary particles. Mokka also stores hits from secondary particles. Due to the way they are created by SensitiveDetector class in Mokka they are not on the exact detector measurement surface as the surface of a hit is calculated as (entrypoint+exitpoint)/2. Secondary particles however come to existence within the silicon and will die there too. So their entry point is not really the beginning of the silicon but already within. The same is true for the exit point. The middle between them is therefore usually not at the exact z-postion of the detector measurement plane. So only if keepHitsFromDeltas is set to true, will hits with a z-position not corresponding to the measurement plane produce TrackerHits. (default value false)
PetalsPerDisk	The number of petals per disk. (Although there are no real petals implemented, hits get a CellID0 corresponding to the petal they would be on.) A value of 1 means there is only one petal spanning the whole disk. The petals start from the x-axis with the beginning of the first petal aligned with the axis. (default value 1)
SensorsPerPetal	The number of sensors per Petal. A petal will be split up into n Sensors, equally distributed. So if the values is 1, there will be one sensor filling the whole petal. If the value is 2, there will be two sensors, splitting the petal at (Rmin-Rmax)/2. As this digitiser simulates a PixelDisk, there there are no sensors at the back. (default value 1)
