cra-tools

This is a collection of tools used for analyzing the angular distribution of cosmic-ray arrival directions.

The project is divided into three subprojects:

TimeScramble

Time-scrambling code for IceCube CRA studies. Currently only reads ROOT format SimpleDST files.

iter-lhreco

C++ implementation of maximum-likelihood technique for reconstructing cosmic-ray anisotropy maps http://iopscience.iop.org/article/10.3847/0004-637X/823/1/10

simpledst-maps

C++ code for extracting data from IceCube's reduced data format (simple-dst) in ROOT/HDF5 and generating local HEALpix maps.

scripts

Collection of scripts for driving production of extraction, reconstruction and analysis of cosmic-ray data.

You will also need:

• CMake >= 3.1
• A C++11-compliant compiler (e.g. gcc >= 4.8.1 or clang >= 3.3)

Installation:

The C++ projects are built using CMake. Each project has a CMakeList.txt that will detect dependencies and generate a MakeFile. To do this cd into the build directory and excecute the commands:

cmake ../src; make
