Repository Content

• code: Contains the Pyspedas and IRFU-matlab packages that were used to downloade and process the data respectively. The zipped files contain the version of the library that were used to generate the latest figure and analysis shown in the manuscript.

• figures: Contains a step-by-step guide on how to fully reproduce the figures of the work. Figures will be uploaded after the publication of the manuscript.

Extra information

For fully reproducing the figures the irfu-matlab library can be used, available at irfu-matlab. After adding the library to MATLAB's path one needs to run:
