Routines for analyzing the radio frequency interference (RFI) environement at the NenuFAR radiotelescope using LT02 (Exoplanets) observations

plot_rfi_stat.py is the main routine. This script performs calculations and plotting of RFI statistical distributions from NenuFAR LT 02 observations.

It includes functions for calculating (rfi_stat_distribution_functions.py) and saving (hdf_functions.py) RFI statistical distributions and for plotting (rfi_stat_plot_distributions_functions.py) these distributions.

The script takes various arguments for controlling the calculations and plotting of the distributions.

Usage:
python plot_rfistat.py [options]

Options: Option | Description --- | ---
-h, --help | Show this help message and exit. --input_sav_file_directory | Input sav file directory location to calculate the distributions (default: "./"). Useful if calculatedistributions keyword is True `--inputhdf5filedirectory| Input hdf5 file directory location to plot the distributions (default:"./"). Useful if calculate_distributions keyword is True -rfilevel| Level of RFI mitigation (required). --ouputdirectory| Output directory (default:"./"). --colormap| Color map for plots (default:'viridis'). --calculatedistributions| Keyword to calculate and save the distributions (default:False). If False, and plot_distributions keyword is True, the plotting function will try to load pre-calculated distribution from hdf5 files. --calculatedistributions| Keyword to plot the distributions (default:False). --localtime| Keyword to plot only on local time (default:False). --azimuth| Keyword to plot only on azimuth (default:False). --elevation| Keyword to plot only on elevation (default:False). --elaz| Keyword to plot only on elevation vs. azimuth plane (default:False`).

If --local_time, --azimuth, --elavation and --ezal == False, the plotting functions will plot all these distributions

Example:
python plot_rfistat.py -rfi_level 0 --calculate_distributions --plot_distributions --local_time --azimuth

Requirements: * python 3.8.10 * pip install -r requirementspackagesexoradio.txt
