Atmospheric Neutrino Monte Carlo Simulations

We provide the MC simlation files of atmospheric neutrinos for the following experiments in HDF5 (https://www.hdfgroup.org/solutions/hdf5/) format. 

IceCube-Upgrade: Copied from publibly available simulation from the [IceCube Collaboration](https://icecube.wisc.edu/data-releases/2020/04/icecube-upgrade-neutrino-monte-carlo-simulation/) converted into .hdf5 format for completeness.

ORCA: Projected simulation based on IceCube-Upgrade's upgrade Monte Carlo applying reported detector response.

SuperK: Simulation of fully-contained (FC) events with no neutron tagging covering the first 3 phases of the experiment. It can be used as simulation for Hyper-Kamiokande scaling the weights accordingly (x8.3).

SuperK with neutron tagging on Gadolinium: Simulation of fully-contained (FC) events with neutron tagging on gadolinium (80% efficiency) assuming the SuperK detector is loaded with Gd at the goal concentration of 0.1%.

SuperK with neutron tagging on Hydrogen: Simulation of fully-contained (FC) events with neutron tagging on hydrogen (~24% efficiency) for phases 4 and 5 of SuperK and also used as HyperK's simulation file scaling the weights accordingly (x8.3).
