cramer-rao C++ API Reference

class CramerRao : public I3ConditionalModule
#include <CramerRao.h>

calculates estimator

This module calculates an estimator for track resolution using Cramer-Rao inequality. Further informations can be found on http://butler.physik.uni-mainz.de/I3Wiki/index.php/Estimation_of_resolution_and_likelihood_as_cut_parameter

options:

InputResponse: Name of PulseSeries or HitSeries

InputTrack: Name of InputTrack

OutputResult: Name of output

AllHits: if this option is selected DOMs are weighted with number of hits

z_dependent_scatter: if this option is selected a depth dependent scatterlenght is used

PathToTable: If I3_SRC is set at your system, you don’t need this. Else you have to copy the tables that are used for calculation somewhere and than set the path directory. The tables are in resources/data/.

DoubleOutput: if this option is selected the estimated standard deviations “cramer_rao_theta” and “cramer_rao_phi” are written out as doubles. These can be easily included into flat-ntuples.
