@gpapadok Thanks for the PR.

This example is indeed really old. I think that it would benefit from a full rewriting by removing all options to use it as a script, rewrite it into smaller and easier code cells, and add the explanations next to the code cells then.

Such rewriting would require more time. I propose to merge this PR first. @gpapadok would like to contribute a rewriting of the example? If not, we will add this example into a pool of examples that needs to be revamped.

@glemaitre Edited as requested.

I will update the example too and make a separate PR.

Thanks @gpapadok.

This is good to be merged as a first iteration.
