ethanka0 / matching_grb_frb_script

Script designed to process CHIME FRB catalog and Fermi LAT data which can be modified for any high energy astrophysics event searches.

matching_grb_frb_script

matching_frbgrb_finder_python.py

This python script can be used to find overlapping events between 2 catalogs. It compares the location (RA/DEC) and time of event to find any similarities. It is used in step 2 of my analysis into the "Search for Gamma-ray Emissions from a Population of Fast Radio Bursts."

Usage requirements:

• The script requires .csv files and knowledge of what column contains the GRB/FRB code, the event time, RA, DEC, and RA/DEC errors.
• Input a time uncertainty when prompted, filenames, and number of entries in each file
• The script displays when a match is found and it will output a total runtime at the end as well as the time the script finished
• The package 'pandas' is required which can be installed here: https://pandas.pydata.org/getting_started.html
• Generates 2 .txt files, one containing photons and FRBs that only match in location and the other containing photons and FRBs that mathc in both location and time.

matching_frbgrb_finder_bash.sh

This bash script utilises the Fermi tool 'gtselect' and is much more optimised than the python version above. It is used in step 2 of my analysis into the "Search for Gamma-ray Emissions from a Population of Fast Radio Bursts."

Usage requirements:

• Have Fermi tools pre installed and he conda enviornment activated (https://github.com/fermi-lat/Fermitools-conda/wiki/Installation-Instructions)
• Activate Fermi enviornment
• Input a time uncertainty and energy range when prompted
• Requires the data and knowledge of what column contains the GRB/FRB code, the event time, RA, DEC, and RA/DEC errors.
• The script can be adapted by changing the lines with comments.
