Detailed Description

Fill the residuals of the hits into an AIDA histogram.

Remember that LCIO::TRBIT_HITS has to be set, so the hits are stored. If ApplyCorrectionFactor is set the bias is corrected by , where dof is 2 for a straight line, 3 for a helix in xy, and 2 in z for all cases.

Input - Prerequisites

• A Collection of reconstructed tracks (LCIO::Track)

Output

• Histograms of the residuals in the xy-plane and in z

Parameters

InputTrackes	Name of input Tracks collection (default: TPCTracks)
ReferenceTrackRelationsColName	(optional) Name of the collection with relations to reference tracks (MC truth or hodoscope)
HistogramMinValueXY	Minimum value in xy histogram (default: -0.3 mm)
HistogramMaxValueXY	Maximal value in xy histogram (default: 0.3 mm)
HistogramMinValueZ	Minimum value in z histogram (default: -1.0 mm)
HistogramMaxValueZ	Maximal value in z histogram (default: 1.0 mm)
ApplyCorrectionFactor	Multiply residual with (default: true) Attention: Turn the correction off when using reference tracks!
DoFXY	Degrees of freedom in the XY plane (2 for straight line, 3 for helix) (default: 3)
