We got a report from Jackie Brossamer and Marge Shapiro that this
analysis seemed to have mangled ref data. Looking into it, the HepData
data table was obviously corrupted, so I got Mike to fix it and
re-dumped the data file (getting some fixes into the HepData YODA
formatter at the same time.)

Ok, thanks.

I have a feeling there were a couple of others which were manually
modified but I have no record of which ones :-/
