![]() ![]() TrueActiveLengthAfter ¶ĭistance from most closest position of a neutrino trajectory to IceCube center to the exit of detection volume. TrueActiveLengthBefore ¶ĭistance from most closest position of a neutrino trajectory to IceCube center to the entrance of detection volume. Total energy loss of Tau particle before it decayes (end energy of the tau track). (not a closest position of InIce Track or Cascade) EnergyLost ¶ ![]() ![]() Used muon range in for InIce Neutrino Energy ImpactParam ¶Ĭlosest distance from InIce neutrino trajectory to IceCube center Used muon range converted to length for InIce Neutrino Energy RangeInMWE ¶ Geometrical length from the entrance position of the detection volume to the interaction vertex position RangeInMeter ¶ Interaction type (integer, see EnumTypeDef.h) LengthInVolume ¶ InteractionXsectionCGS ¶Ĭross section of selected interaction at the interaction vertex. Total cross section at final interaction vertex. InteractionColumnDepthCGS ¶Ĭolumn depth from the entrance position of the detection volume to the interaction vertex position. The value is used to calculate TotalWeight. Total column depth within detection volume. Out_lepton_E = (1 - y) * nu_energy TotalColumnDepthCGS ¶ (used to calculate outgoing angle between InIce neutrino and a secondary track) BjorkenY ¶ Bjorken’s Y parameter for final interaction. See InteractionBase::SetSecondaryLepton() for how it is used. Interaction info at detection volume (final interaction) ¶ BjorkenX ¶ījorken’s X parameter for final interaction. Injected 100 NuTau and only one NuTau is selected to process NuGen, and regeneration process increased the child neutrinos N : NInIceNus = 100 + N -1 (-1 for removing double counting of selected neutrino) Injected one NuTau and regeneration process occurred, arrived N nus : NInIceNus = N Number of arrival neutrinos to the detector. Latest I3MCWeightDict contains minimal primary information required for weighting process.įollowing parameters are for point source only, the input direction info. Power law index of primary neutrino (generation flux) Primary particle info ¶ Primary energy range in log10 PowerLawIndex ¶ Primary azimuth range MinEnergyLog, Ma圎nergyLog ¶ Primary zenith range (for diffuse source) MinAzimuth, MaxAzimuth ¶ If the source is pointsource, this parameter is set to 0 (to make consistent with definition of OneWeight) MinZenith, MaxZenith ¶ Injection area of primary neutrino, in cm^2 SolidAngle ¶ Height of injection cylinder (for CIRCLE injection mode) or detection cylinder (for SURFACE injection mode) InjectionAreaCGS ¶ Radius of injection cylinder (for CIRCLE injection mode) or detection cylinder (for SURFACE injection mode) CylinderHeight ¶ If you use OneWeightPerType parameter instead of OneWeight, you don’t need to compensate the factor. atmospheric neutrino flux), the required number of event per file should be “per particle type” (it is known as famous factor 2 for atmospheric neutrino weight). When you weight with “per particle type” (e.g. NEvents ¶ĬAUTION:This is total number of events per file, with neutrino and anti-neutrino. These parameters may be stored in s-frame, because they are not eveyt-by-event parameters. Renamed to RangeInMWE Parameters should be same for all events in a file ¶ TotalDetectionLength = TrueActiveLengthBefore + TrueActiveLengthAfter ![]()
