PISA

IceCube oscillation analysis suite

PISA is a software written to analyze the results (or expected results) of an experiment based on Monte Carlo simulation.

In particular, PISA was written by and for the IceCube Collaboration for analyses employing the IceCube Neutrino Observatory, including the DeepCore and the proposed PINGU low-energy in-fill arrays. However, any such experiment—or any experiment at all—can make use of PISA for analyzing expected and actual results.

PISA was originally developed to cope with low-statistics Monte Carlo (MC) for PINGU when iterating on multiple proposed geometries by using parameterizations of the MC and operate on histograms of the data rather than directly re-weighting the MC (as is traditionally done in high-energy Physics experiments). However, PISA’s methods apply equally well to high-MC situations, and PISA also performs traditional re-weighted MC analysis as well.
