[Brahms-dev-l] BRAT bumped to 2.17.9; new cent calibrations

Hi,
I just bumped brat to 2.17.9 with the addition of a number of changes 
needed to use the
flow si detectors, together with the normal si and tile detectors, to 
calculate the reaction
centrality for the yr04 runs.

Previous centrality calculations for the yr04 runs should be discarded. 
   The current calibration
for the 200 GeV data reproduces our earlier dN/dEta measurements at 
this energy, although the
TMA numbers are 5-10% low.  (The low TMA values was also found with the 
dAu runs and may
reflect some aging effect for the plastic scintillators.)
The calibration for the 63 GeV data will see some small changes over 
the next day as it is
fine-tuned.

The runs used for the mult/cent calibrations are:
200 GeV:
     9389
     9701,9702
63 GeV;
    11298
    11523

I feel confident about the energy calibrations for these four runs, but 
still need to work
some on the mult-to-cent calibrations, especially for the 63 GeV data.

The brat macro that I'm using for the calibrations is
/brahms_app/sjs_app/macros/MultCalibration.C

As always, it is a good idea to check the centrality calibration for 
any given run
by doing a short replay of min bias events (trig 4 for yr04) and seeing 
a nice
flat behavior for the cent spectrum.  This is especially important 
until we have a
chance to systematically check the calibration for all runs.  
Unfortunately, I am seeing
evidence of significant pedestal drift and some gain changes over time. 
  Runs other than those
listed above have not been individually calibrated.

Regards, Steve
