Ben Smith | Problem Fixed | General | Evening data taking, purity check | > Not sure if the trigger threshold is correctly set, there is an error:
Sorry, I made a change to the baseline calculation and forgot to update the threshold tool. It's updated now.
The thresholds currently seem to be set to 12801 - this is 2699 below the nominal baseline of 15500. |
