Detailed Description

A pre-clusterizer of Geiger hits for the SuperNEMO detector.

This algorithm aims to group the Geiger hits in a given SuperNEMO event record using some simple clustering criteria:

prompt hits are grouped within a prompt pre-cluster if they lie on the same side of the source foil,
delayed hits are grouped within a delayed pre-cluster if they lie on the same side of the source foil and are in a 10 us time coincidence window. Only two prompt clusters can exists (maximum: one per side of the source foil). There is no limitation on the number of delayed clusters.

The TrackerPreClustering::pre_clusterizer object is configured through a TrackerPreClustering::setup_data object.

The input of the algorithm is implemented through the template TrackerPreClustering::input_data<> class which is basically a collection of Geiger hits.

The output of the algorithm is implemented through the template TrackerPreClustering::output_data<> class which stores collections of prompt and delayed clusters. By default the tracking chamber is considered as splitted in two parts.
