please find attached a short document on how to identify which ESD quadrant we are driving from the slope of the 'oplev deflection vs VBIAS' plots we obtain during the ESD charge measurements. We know that the quadrant labelling on the Epics channels and MEDM windows do not correspond with the actual ESD quadrants being driven and the discrepancy is different between ETMX and ETMY.
