Hi. Thank you for the contribution.

You've created your own repository to solve the exercises proposed by lemouth, but is clear that your post is promoting the [MadAnalysis 5 framework](https://github.com/BFuks/madanalysis-utopian). For this reason, I think that you should add the MadAnalysis 5 framework repository in the first sections of your posts, instead the [https://github.com/BFuks/mad5-utopian-exercises](https://github.com/BFuks/mad5-utopian-exercises) repository, and, obviously, add the links to your own repository with the exercises solution in the sections that you consider it necessary.

It's great to find this kind of contributions here and see the way that lemouth is supporting the contributors and participants in the project, this is an open learning process that allows many things to be clear to the readers.

This post can be considered an extension of your previous post, [Particle physics - exercise 1c solution](https://steemit.com/utopian-io/@irelandscape/particle-physics-exercise-1c-solution), so considering that it's about corrections of your previous proposal, and that the volume of work in this post is minor, the score for this post will be a bit lower.

Thank you for your efforts and keep up the good work.
