Update NuMI flux files, weights, and systematics for the new version G4NuMI

[woodtp]

For NuMI MC productions, we should use a flux simulation based on the main_modern_g4 branch of G4NuMI.

This will require us to

• Update the paths here

  icaruscode/fcl/gen/numi/genie_icarus_numioffaxis.fcl

  Line 60 in afd294f

  FluxSearchPaths: "/cvmfs/sbn.osgstorage.org/pnfs/fnal.gov/usr/sbn/persistent/stash/physics/beam/GENIE/NuMI/standard/v02_00/"

  and here

  icaruscode/fcl/gen/numi/genie_icarus_numioffaxis.fcl

  Line 95 in afd294f

  icarus_genie_NuMI_RHC.FluxSearchPaths: "/cvmfs/sbn.osgstorage.org/pnfs/fnal.gov/usr/sbn/persistent/stash/physics/beam/GENIE/NuMI/standard/v02_00_RHC/"

  to point to the new flux files located in /pnfs/sbn/persistent/stash/physics/beam/GENIE/NuMI/standard/v03_00.

Note

These next two are not a prerequisite for production, but still need to be done at some point.

• Update the files in beamData/NuMIdata to include the new flux weights and systematics from PPFX.
• Remove the beam_power systematic from sbnana/sbnana/CAFAna/Systs/NuMIFluxSysts.cxx, as it's not longer needed since the new flux simulation includes the 1MW beam geometry.
