Detailed Description

Resoltuion calculator for straight lines using the gemetric mean method.

Determines the resolution via the geometric mean method. Only possible for straight line tracks!

Todo:

Currently only the histograms are filled. The resolution propper has to be calculated manually.

One can apply a cut in z direction. If this is used to create several z bins by using several instances of HitAndTrackChargeProcessor in the steering file, you have to apply unique names for HistoGeoN and HistoGeoNminus1 for each instance.

Input - Prerequisites

• A collection of tracks (lcio::Track).
  Remember that LCIO::TRBIT_HITS has to be set, so the hits are stored.

Output

• Histograms with residual distribution including all hits (n) and leaving out the test hit (n-1)

Parameters

InputCollectionName	Name of input collection, TrackerRawData
ApplyZCut	Flag whether to cut in z , default 0
ZMin	Minimal: z value, default 0 mm
ZMax	Maximal: z value, default 100 mm
HistoGeoNName	Name of the histogramm with all hits in the track fit , default histoGeoN
HistoGeoNminus1Name	Name of the histogramm with n -1 hits in the track fit, default
HistoRange	Histograms will have range (-_histoRange, _histoRange), default _histoRange = 1mm
HistoBin	Histograms will be binned with _histoBin, default _histoBin = 100
DisplayAllEvents	Flag whether a Event Display shall be created in any Case
HistoGeoZNName	Name of the histogramm with all hits in the track fit
HistoGeoZNminus1Name	Name of the histogramm with n -1 hits in the track fit
transDiff	transverse Diffusion coefficent mu per sqrt(cm)
longDiff	longitudinal Diffusion coefficent mu per sqrt(cm)
