If you ignore the pT spectra, I'm pretty sure you can get reasonable
results from two independent runs with the CDF_2001 analysis: one for
the min bias plots with CKIN(3) = 0 (== unset), and one for the JET20
data: without a merging run around 30 GeV, the upper end of those histos
will go a bit wobbly, but a CKIN(3) = 15 cut should give reasonable results.

Actually, I've just been using that as the test analysis for the runs in
the validation system ;) It's definitely a good one for the reasons
you've given.

Okay --- it's not going to be a meeting with an agenda, anyway, and we
have more time over the following day and a half. I would personally
like this time since it means I can get some group feedback on the plots
I will show before the MC meeting.

That's good... we should start jobs running for Py6-pT as soon as
possible: Wuppertal's batch system isn't receiving its usual hammering
from us at the moment! I also think we should include CDF_2004 (except
"Swiss Cheese -3") this time... most of the plots are looking good and
it's nice to have the option of using the data. Let's continue this on
the Professor list.
