Results and analysis scripts for FRB121102 burst analysis.

FRB121102

This repository contains the data and analysis scripts used in the paper (here).

Here is a link of the raw observation files.

See the project webpage with burst fitting results: FRB121102

Here is the layout for this repository:

• analysis/: consists of the following analysis notebooks and scripts:

Notebook	Description
waittime_analysis.ipynb	Analysis of wait time distribution of bursts
period_search.ipynb	Period search on bursts
burst_rate.ipynb	Burst rate estimation using Poisson and Weibull distributions
cumulative_energy.ipynb	Cumulative energy calculation for the bursts and estimation of power law slopes
param_wrt_time.ipynb	Plot of burst parameters with respect to time
make_param_dict.ipynb	Read the MCMC results (h5 files with samples) and generate csv files with burst properties
make_prop_table.ipynb	Read the burst parameter csv and generate Latex table for the paper
cumulative_corner_plot.ipynb	Read MCMC posteriors and generates a combined corner plot with all burst properties
mcmc_fitall.py	Python script used for MCMC burstfit. It reads in the candidate h5 files generated by your_candmaker.py during the search step, and uses burstfit to estimate the properties of the bursts

• data/: consists of all_bursts_bary.csv file with all burst properties. Each row correspond to a unique burst component. Each column shows a burst property, or 1-sigma fit error on a property. Individual bursts have a unique cand_id. bidx corresponds to the burst index used in the paper.

• Posterior sample chains generated by burstfit-MCMC on all bursts are available upon request (145G).

• fit results and corner plots: See project webpage here.
