Description

### Environment: (where does this bug occur, have you tried other environments)
- Which branch (often `main` for latest released): `main`

### Steps to reproduce: (give a step by step account of how to trigger the bug)
Check the Q2 distributions; this is added to the CI in #246

### Expected Result: (what do you expect when you execute the steps above)
A distribution similar to ePIC, **not** radiative corrected:

### Actual Result: (what do you get when you execute the steps above)
Here is ePIC, with radiative corrections **enabled**:
![canv_Q2___histos__finalState_0__ptLab_0__w_0__xF_0__y_0__z_0 epic_arches_radcor](https://user-images.githubusercontent.com/7843751/214448189-d9e77608-8246-43f4-895f-0f1fd49e7c2d.png)

See artifacts from https://github.com/eic/epic-analysis/pull/246 for others; the best test is ePIC Arches (since the BryceCanyon files are too big)
