Right. I see no reason not to...

That sounds good!

I recognise the diffractive and inelastic QCD processes from there, but
11-13 and 28, 53, 68 are new to me... do you know offhand what those
are? Are they things that we should include when running PYTHIA on other
min bias analyses? Usually we just set up with MSEL=1 or =2 (or turn on
the 92-95 components to exclude 91 (== elastic scattering) just for
computational efficiency... the AGILe fpythia-minbias.params file does
just that.

I should get my copy of AGILe back in action over the weekend,
hopefully, along with other tuning things to do (and presumably dodging
Jo's wrath for working at the weekend!) so I'll let you know if I get a
chance to check this out for you. Otherwise let me know if you get a
chance to test it yourself... doesn't Sherpa have a clever new soft
physics model to try out? ;)
