Entry number 309507

run 1236: finally, a good run with the qweak adc configuration handled 
correctly and the pedestals properly calculated and updated from yesterday's 
run (1218). 

Fig. 1-2 show that the signal size in bpm1I02 is reasonable, as expected.  I 
include it because the comparison is a little subtle: the bpm wiresum for vqwk 
adcs divides by the number of samples, whereas the individual wire signals are 
only put in the tree without pedestal subtraction.  These two plots differ by 
the pedestal subtraction which, as expected, totals about 100e6 or so.

There is no pair-synch separation in the wiresum asymmetry or position 
differences.  There isn't a lot of information at 30 Hz to suggest why the 
position jitter should be so large.
