For 2019 run
Beam energy reported by MCC: 4.556651 GeV
Beam energy to field setting conversion from above documents: B = Eb * 0.22727 Tesla/GeV = 1.03559 T = 10355.9 Gauss.
Analyzing magnet current: was set to 1592.37 A, the current readback was 1609.576±0.058 A, Magnetic Field read back: -9668.1±21.3 G
Calculated field from current: ( 1592.37 - 0.6657)/0.1537 =10355.9 Gauss.
The field map used for 2019 is 418acm2_10kg_corrected_unfolded_scaled_1.0319, so uses 10319 Gauss field (0.36% low).
(Method for average field and current read back: take the MYA current and field probe read back for the Analyzing Magnet (PSPECIRBCK, HPS:LS450_2:FIELD) for the period 2019-07-26 19:08 until 2019-09-08 21:26. For each run, search for a value before the run_start time. Compute average and std for those values that are > 1599 (current) or < -9000 (field).)
