    keyword=Rarm alignment plots from last night

    After modifying my macro to cut on upper quartz ADC (instead of lower), just as Bob did last night, I get these alignment plots. Because of the lack of separation between the ADC signal and pedestal for the upper signal, the quartz shadow (red trace) is not as clean as usual...also my feeling is that the alignment is ok (just as Bob stated), but we may want to recheck this after fixing the lower quartz ADC. Jon and Ahmed, do you guys have any idea why the lower quartz signal is messed up?
