Hi Collaborators, I'm really glad that I read this mail now. I just reduced and ran a quick reco on 5757 and could not understand the spectra at all. If the magnets were off, I guess that would explain things. And now that I see that this is the reason for the odd spectra, I'll spend the last hour of my weekend on something more enjoyable. I think this episode tells us that we need to (somehow, and I don't know how) have the actual current (or field) readings in the database. This is the second time that I know of that we have run with zero field, even though the log and the data base show that the magnets were on.
