    keyword=Charge asym as measured by parity and HRS DAQs

    While we were taking data tonight, I ran the parity DAQ (run 7039) and measured 
the charge asymmetry while we were taking data with the spectrometer DAQ (run 
2406).  The charge asymmetry was measured to be -139 +/- 2.9 ppm by the parity 
DAQ (fig. 1) and -112 +/- 569 ppm (fig. 2, bottom left) by the spectrometer DAQ 
(per Bob's macro).  The resolution isn't good for the spectrometer DAQ, so it's 
hard to say if they're really seeing the same charge asymmetry.  I didn't have 
the chance to make the charge asymmetry really large, so this is all the data 
for now.  It seems that things are working ok, but further analysis/tests are 
probably necessary or at least a good idea.
