[Rivet] mcplots - Problem with the OPAL 2004 Rivet analysis ?

yes, we do. That is, as I mentioned in my mail back then, the reason we
asked you to test 1.5.1a0.

Feel free to include or exclude whatever you like.

In both, though the error in ALEPH probably doesn't change anything
visibly.

Into both analyses.

It has been identified and that's the only reason why we haven't
released 1.5.1 yet. We plan to fix it this week and release then.

Cheers,
