icecube.simprod.segments.GenerateNoiseTriggers module

icecube.simprod.segments.GenerateNoiseTriggers.CheckEventTime(frame, TriggerHierarchy='I3TriggerHierarchy', MCPESeriesMap='I3MCPESeriesMap')

If the trigger exists within 20 microseconds of the first or last hit, then we need to remove that trigger. Otherwise events will include a non-simulated region in the event window and things will just be wrong.

Parameters:

  • TriggerHierarchy – Name of the I3TriggerHierarchy in the frame.

  • MCPESeriesMap – Name of the I3MCPESeriesMap to check for earliest/latest hits.

icecube.simprod.segments.GenerateNoiseTriggers.NoiseWeight(frame, NEvents)

Write a weightmap to the frame for the noise triggers. REQUIRED for the CoincidenceAfterProcessing module. This should only depend on the number of events, since there’s no physics or flux models to worry about to first order. There is also a “time buffer”, which is meant to take into account edge effects of triggers near the frame edges.

Parameters:

NumEvents – Number of events being produced for this file

icecube.simprod.segments.GenerateNoiseTriggers.ProduceNoiseTriggers(tray, name, gcd_file, nevents=1, run_id=None, filter_trigger=True, mdomNoisePath='/cvmfs/icecube.opensciencegrid.org/users/gen2-optical-sim/geant_noise/npy/211217_mDOM_Noise_newPMTs_wQE/*.npy', lom16NoisePath='/cvmfs/icecube.opensciencegrid.org/users/gen2-optical-sim/geant_noise/npy/220725_LOM16_vitrovex_goodPMTs/*.npy', lom18NoisePath='/cvmfs/icecube.opensciencegrid.org/users/gen2-optical-sim/geant_noise/npy/220804_LOM18_vitrovex_goodPMTs/*.npy')

ProduceNoiseTriggers: Create events containing only noise and no simulated particle interactions. These are needed for low-energy DeepCore and PINGU simulation due to a lower detector threshold. There are some nuances to this. All events must be long in order to avoid problems at the edge of simulated events where expanding around the triggers could include unsimulated regions in time. All frames are initially 100 ms long. These are triggered, then cut down by CoincidenceAfterProcessing to be more reasonable lengths.

Parameters:

  • name – Name to add to all of the modules.

  • gcd_file – The location and name of the GCD file to use

  • mjd – Modified Julian Date to put into the I3EventHeader. Start of IC86-1 by default.

  • runID – The run number to put into the I3EventHeader.

  • nevents – The number of events to simulate.
