MuonGunGenerator¶
The IceProd module MuonGunGenerator
generates single atmospheric
muons with MuonGun
and propagates them through the ice with
PROPOSAL
by calling the GenerateCosmicRayMuons and
PropagateMuons tray segments in its execution method,
respectively. Finally, the module writes an I3File
containing only Q-frames; each Q-frame contains the following frame
objects:
I3MCTree
MMCTrackList
RNGState
muongun_weights
Example¶
A basic example script; the module’s parameters can be changed via the command line:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import logging
import icecube.simprod.modules
logging.basicConfig(level=logging.INFO)
if __name__ == "__main__":
mu_gun = icecube.simprod.modules.MuonGunGenerator()
# Change some default values.
parser = mu_gun._opt_parser
parser.defaults["nevents"] = 100
parser.defaults["outputfile"] = "muongun_fullchain.i3.gz"
parser.defaults["summaryfile"] = "muongun_fullchain.xml"
stats = {}
mu_gun.ExecuteOpts(stats)
for key, val in stats.iteritems():
print "%s: %s" % (key, val)
