keyword=Detector asymmetry widths
Detector widths are unequal; for example, in run 5640 (raw asymmetries):
det1 908
det2 1921
det3 1171
det4 1145
Detector combination asymmetries are calculated in the analysis using weights,
but at present all weights are set to 1. For the right arm (det3 and det4)
this is fine, but not for the left arm. Before we balanced the HV the
difference in signal size effectively gave roughly good weights, but now the
results are bad: det_l width comes out to 1068.
Re-analyzing with weights .8 .2 1 1 gives det_l width 829.
We probably should set default weights something like this in the database.
