* At 100% solenoid field take 30 of data at the highest current authorized by the SVT/MM folks (ensuring that the DC and other detector currents/rates are acceptable). Select the trigger file based on high threshold ECAL clusters (to select electrons). Contact the DAQ expert to set this up. | * At 100% solenoid field take 30 of data at the highest current authorized by the SVT/MM folks (ensuring that the DC and other detector currents/rates are acceptable).

- Note, all non-JLab numbers must be dialed with an area code. When calling from a counting-house landline, dial "9" first.
- To call JLab phones from outside the lab, all 4-digit numbers must be preceded by 757-269
