level3-filter-cascade

• Release Notes

Introduction

The aim of the Cascade L3 processing is to reduce the size of the dataset (at least by factor of 30) while maintaining the atmospheric and extraterrestrial signals efficiency as high as possible, in order to have a fast processing and no storage problems.

The idea is to use Toplological Splitter module first and identify coincident events: number of output splits maps corresponds to number of sub-events found. Detailed description of the Topological Splitter method for identifying coincident events can be found here.

After identifying event “multiplicity” we run VetoModule from CascadeVariables project and separate events

The general flowchart of L3 cuts for IC86 2011 - present is shown below:

Detailed Cascade L3 flow chars is shown below:
