icecube.genie_reader.I3GenieReaderSegment module

icecube.genie_reader.I3GenieReaderSegment.I3GenieReaderSegment(tray, name, GenieFileGST='', GenieFileGRooTracker='', SystWghtFileNameList=None, GenieInfo=None, IceDensity=5.804604062395718e+30, RandomService=None, ResultDictName='I3GenieResult', SystWghtDictName='I3GenieSystWeightDict', MCTreeName='I3MCTree', MCWeightDictName='I3MCWeightDict', OutputResultDict=True, OutputSystWeights=True, GenVolCenter=I3Position(0, 0, 0))

Reads GENIE Generator variables and then adds systematic weights from GENIE ReWeight.

Requires both GST and GRooTracker root-files to read generator variables.

For systematic weights requires ReWeight output root-files.

Parameters:

  • GenieFileGST (str, default='') – Name of the GENIE gst file to read events from.

  • GenieFileGRooTracker (str, default='') – Name of the GENIE gRooTracker file to read events from. Assumes that it is converted from the same GHEP file as the input gst file.

  • SystWghtFileNameList (list of str, default=None) – List of names for the GENIE reweight files to use. Assumes that they are generated for the same GHEP file as the input gst and gRooTracker files.

  • GenieInfo (I3GenieInfo (struct), default=None) – I3GenieInfo object with generation info (defined in simclasses).

  • IceDensity (float, default=0.93*I3Units.g/I3Units.cm3) – Ice density.

  • RandomService (default=None) – The I3RandomService we are going to use.

  • ResultDictName (str, default="I3GenieResult") – Name of the output I3GenieResult frame object.

  • SystWghtDictName (str, default="I3GenieSystWeightDict") – Name of the output systematic weight dictionary.

  • MCTreeName (str, default="I3MCTree") – Name of the output I3MCTree frame object.

  • MCWeightDictName (str, default=I3MCWeightDict") – Name of the output I3MCWeightDict frame object.

  • OutputResultDict (bool, default=True) – Choose whether or not to output I3GenieResult.

  • OutputSystWeights (bool, default=True) – Choose whether or not to output I3GenieSystWeightDict.

  • GenVolCenter (dataclasses.I3Position, default=I3Position(0.,0.,0.)*I3Units.m) – I3Position of generation volume center.
