Periods

The periods in BOLD are calibrated i.e. have a pedestal and gain tables. Each period corresponds to constant FCAL and/or experimental conditions.

• period 0: (empty Be target)
• period 1: (empty Be target)
• period 2: 110498-110549 (Be target - B-field ON)
• Period 3: 110553-110583 (Be target - B-field ON, FCAL HV change)
• period 4: 110585-110599 (Be target - B-field ramping down)
• period 5: 110600-110621 (Be target - B-field OFF)
• period 6: 110637-110640 (He target cooling - B-field ramping up, FCAL HV change)

• period 6
• period 8

Bad block map

This map is done for each run number by combining the info collected by analysing the LED and pi0 skims.
