1237	12/23/2020	~2 hr 42 min	~1500k	(140,30) and (800,800)	-1850 V, -1200 V, -1100 V, -1000 V	Voltages calibrated from run 1235	Voltages calibrated from run 1235	0
1235	12/21/2020	~2 hr 46 min	~1500k	(140,30) and (800,800)	-1850 V, -1200 V, -1100 V, -1000 V	left half = Calibration_Results_Run989_Save.txt, right half = -1500 V	left half = Calibration_Results_Run989_Save.txt, right half = -1600 V	0	The F1 seems to miss fADC pulses sometimes. Seems more on right half.
