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 ofall_bursts_bary.csvfile 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 uniquecand_id.bidxcorresponds 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.
