Subject: d0sim settings for p11.13 MC


Hi Ia,

Concerning your question about the recommended d0sim parameters for
p11.13 Monte Carlo, I can certainly tell you what are the numbers
that CTF used to produce the CTF09 files.

As you could see in the CTF meeting yesterday, the first look at the
noise/zero suppression aspects was encouraging, but various properties
of jets did not completely match between data and MC (which may be a
different issue). We will try again with a higher pt QCD sample.

For CTF09 productions we modified 4 params in 
p11.13.00/pileup/rcp/MergeMinBias.rcp

New values:
Electromagnetic_cut=1.37     (ie 1./1.54*2.1)
Hadronic_cut= 1.29          (ie 1./1.77*2.3)
rms_scale_factor=1.0
zs_scale_factor=1.0

As far as I know, the modification was achieved by mc_runjob settings 
(new entries in the 09 ctf.sra.script file for d0sim at UTA, if such script
file has a meaning to you):

cfg d0sim define float PileupEMCut 1.37
cfg d0sim define float PileupHadrCut 1.29
cfg d0sim define float RMSScaleFactor 1.0
cfg d0sim define float ZSScaleFactor 1.0

I am cc'ing Mark so that he can holler if I've spcified this incorrectly...
I also asked Mark to generate the ttbar->e4j sample that you wanted -- 
hopefully we can look at it before the top group requests the official 
farm production (not to mention the CTF internal interest).

Let me know if you have any questions or comments.
Marek
