Gravitational lensing: towards combining the multi-messengers (data sharing)

# Gravitational lensing: towards combining the multi-messengers (data sharing) This repository contains the data and code to plot Fig. 1 and Fig. 4 from the article titled - "Gravitational lensing : towards combining the multi messengers". The two folders included here are described below. ## 1. delta-psi - This folder contains the data and code to plot Fig. 1 in the paper. - To generate plot for Fig. 1, run python plot_fig1.py - It computes the y-axis ($\delta \Delta \psi$ : uncertainty in the determination of the relative Fermat potential) for each combination of image pairs (x-axis), for 3 mock lenses, for each of the 4 configuration which are stored in "PLpert_fig_data" ## 2. grb-gw-lensing - This folder contains the data and code to plot Fig. 4 in the paper. - data-gererator.ipynb generates the data for the plot. This data is stored in "ler_data" folder. Parameters for the GRB-GW lensing system are stored there. - grb-gw-lensing-plot.ipynb generates the plot for Fig. 4 (stored as 'combined-final.png'). It uses the data generated by data-gererator.ipynb. This plot shows, i) detectable lensed GRBs and the associated detectable lensed GW events, and ii) detectable lensed GW events and their associated detectable lensed GRBs.
