Feat/e rosita school updates

[jessicapilling]

This is a tiny change, just adding in two arguments to the expmap command, that were recommended by the eROSITA analysis school

This comment is identical, not sure why it is a change here

I think this is probably because vscode sometimes very annoyingly adds 'non-breaking spaces' rather than just the standard space character - https://stackoverflow.com/questions/57162734/vscode-inserting-non-breaking-spaces-instead-of-regular-spaces

It can be mildly irritating because they don't render as spaces in Pycharm, they just say #NBSP or something like that - doesn't matter here which it is though, and can't tell in the review interface anyway!
