data taken during e'K. Unstable beam x position. Better not use trigger 2 so no need to recalibrate timing |

Optics with 5 pass beam
- E0 = 10.6 GeV, Theta_L = 17 Degrees, Theta_R = 24.00 Degrees
- Sieve in between run 3451 and 3479.
- The BMP Y behaved wired during optics runs. (see log). Per Jason we can use the Harp scan position at (1.4,1.8)see log instead of the BPM to decide the beam position for optics calibration.
