Detailed Description

Resoltuion calculator for straight tracks using the three point method.

Determines the 3 point resolution. Only possible for straight line tracks!

Todo:

Currently only the histogram is filled. The resolution propper has to be calculated manually.

Input - Prerequisites

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

Output

• A histogram with the 3 point residual distribution

Parameters

InputCollectionName

Name of input collection, TrackerRawData

Author

Simone Zimmermann
