Merge branch 'RD-Lb2L1520mue-BGs' into 'main' (again)
Small BG update for Lb2L1520mue analysis
See merge request !192 (merged)
(cherry picked from commit 93f8e4f3)
Reason for cherry-pick: the CI pipeline was cancelled and productions were never created after merging into main. Original merge was manually reverted in commit d561de86.
