| 1470 | 3/9/2021 | ~10 min | ~100k | (170,50) and (800,800) | 100.3 mV | Voltages same as run 1439 (See Link [2]) | 0 | Trigger is the summing module superclusters. Raised threshold to see if left half (145-288) create vertical ADC pattern expected. It seems to be appearing now. |
| 1456 | 3/8/2021 | ~42 min | ~1.5M | (170,50) and (800,800) | 12.5 mV | Voltages same as run 1439 (See Link [3]) | 0 | Trigger is the summing module superclusters. Two halves of HCal look very different. Suspect the threshold is affecting each side differently. |
