    Yesterday, we took took two runs with each of the Compton, the Moeller and the LHRS DAQ. One run was taken with HWP IN, the other one with HWP OUT. For those two runs, the Hall A IA was used to create a large charge asymmetry (800 ppm). Keep in mind that because you used the IA to create the large charge asymmetry, we do not expect the measured charge asymmetry to change sign when the HWP is inserted or retracted. The Compton results are reported in that entry: AQ = +800 ppm.
    The Moeller results are reported in that entry: AQ= -800 ppm.
    The LHRS scaler analysis did not automatically showed up in the end f run for run 8259 nd 8260: AQ= -800 ppm.
