Hi @Marcellocosti , this PR fixes a issue introduced by #17652
The charm-hadron flow task fails when collisions and BCs have different row counts because
BCsWithTimestampsis included directly in the collision joins.Remove the BC table from all three collision joins and provide it as a separate input to the candidate processing functions. Access the associated BC through
collision.bc_as<aod::BCsWithTimestamps>()to preserve the run-dependent resolution updates and candidate-by-candidate SP correction.
