I produced them a while ago and may have managed to mess something up in
between, but they were made using PYTHIA 5423 in AGILe head, with
MSTP(142)=1, which produces pT-enhanced weighted events (thanks to
James). I'm not sure if that's the problem... worth checking. In fact,
generally worth checking the weighted events to see if there are issues,
since when they work they make life *much* easier, especially around the
UE profiles.
