*beep* *bop* Hi human, I ran ruff on the latest commit (15cfb8c04038aa151101ba81af45dd17d68bea38). Here are the outputs produced. Results can also be downloaded as artifacts here. Summarised output:

```diff 11 W191 [ ] Indentation contains tabs 2 E999 [ ] SyntaxError: Expected a statement 1 I001 [*] Import block is un-sorted or un-formatted 1 W292 [*] No newline at end of file ```

Complete output(might be large):

I think the content of the notebook is good, but I would strongly encourage doing the calculations with astropy units, rather than just floats and stating what units the numbers are in in plain text.
