If we want to generalize this a bit, we could remove _low from the name, and change pt_window to a string that takes "low" or "high"

if we generalize this, then the pt_window comparison would change.

I agree that this is right on the border of what might make sense to go in topcofea vs topeft. I guess there's nothing actually strictly analysis specific about it (even though right now it's just being used by one analysis) so probably is fine here. I would pass mass of the Z as an argument though (you could leave 91.2 as the default, as we do in the other pt of the Z mask function), since others might want to use e.g. 91.1876. |

I'm wondering if someone could please comment on the status of this PR? Is it still intended to be merged at some point, or has it been superseded by a different PR in topcoffea and/or topeft? |

Hi @kmohrman, This branch's function is implemented in a new branch. So it's not going to be merged. We can delete it. Thanks for checking! |

Ok, thanks for the update! Just to confirm, are you ok the PR being closed and its associated branch (3l-offZ) being removed from the topcoffea repository? Or did you still need the branch as a reference? |
This PR is crucial for the update of analysis including the division of 3l event categories.
The changes are made in
event_selection.pyto add an extra masking for low mass region of 3l-offZ channels (to use in the analysis processor in topeft).
