# FRB121102
This repository contains the data and analysis scripts used in the paper ([here](https://arxiv.org/abs/2107.05658)).
[Here](https://zenodo.org/record/5029530) is a link of the raw observation files.
See the project webpage with burst fitting results: [FRB121102](https://thepetabyteproject.github.io/FRB121102/)
Here is the layout for this repository:
* [`analysis/`](https://github.com/thepetabyteproject/FRB121102/tree/main/analysis): consists of the following analysis notebooks and scripts:
| Notebook | Description |
| ----------- | ----------- |
| [`waittime_analysis.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/waittime_analysis.ipynb) | Analysis of wait time distribution of bursts |
| [`period_search.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/period_search.ipynb)| Period search on bursts |
| [`burst_rate.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/burst_rate.ipynb)| Burst rate estimation using Poisson and Weibull distributions|
| [`cumulative_energy.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/cumulative_corner_plot.ipynb)| Cumulative energy calculation for the bursts and estimation of power law slopes|
| [`param_wrt_time.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/param_wrt_time.ipynb)| Plot of burst parameters with respect to time|
| [`make_param_dict.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/make_param_dict.ipynb)| Read the MCMC results (h5 files with samples) and generate csv files with burst properties|
| [`make_prop_table.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/make_prop_table.ipynb)| Read the burst parameter csv and generate Latex table for the paper|
| [`cumulative_corner_plot.ipynb`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/cumulative_corner_plot.ipynb)| Read MCMC posteriors and generates a combined corner plot with all burst properties|
| [`mcmc_fitall.py`](https://github.com/thepetabyteproject/FRB121102/blob/main/analysis/mcmc_fitall.py)| Python script used for MCMC burstfit. It reads in the candidate h5 files generated by [`your_candmaker.py`](https://github.com/thepetabyteproject/your/blob/master/bin/your_candmaker.py) during the search step, and uses [`burstfit`](https://github.com/thepetabyteproject/burstfit) to estimate the properties of the bursts|
* [`data/`](https://github.com/thepetabyteproject/FRB121102/tree/main/data): consists of [`all_bursts_bary.csv`](https://github.com/thepetabyteproject/FRB121102/blob/main/data/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](https://thepetabyteproject.github.io/FRB121102/).
