i3highesteparticleextractor

Extract the highest energy particle in the event.

class graphnet.data.extractors.icecube.i3highesteparticleextractor.I3HighestEparticleExtractor(hull, mctree, mmctracklist, extractor_name, daughters, min_e, **kwargs)

Bases: I3Extractor

Extract the highest energy particle in the event.

Initialize the extractor.

Parameters:

• hull (GCD_hull) – GCD_hull object

• mctree (str, default: 'I3MCTree') – Name of the MCTree object.

• mmctracklist (str, default: 'MMCTrackList') – Name of the MMCTrackList object.

• extractor_name (str, default: 'HighestEInVolumeParticle') – Name of the extractor.

• daughters (bool, default: False) – forces the extractor to only consider daughters of the primary particle.

• min_e (float, default: 5) – minimum energy for a particle to be considered, default is 5.

• **kwargs (Any) – Additional keyword arguments for I3Extractors.
