With Marco Meyer-Conde

Due to long-term drift, the beam position of path1/2 in Pcal-X had shifted slightly from its originally designed location.
We confirmed this deviation and adjusted the beam position using the pico motor.

Specifically, we operated picos on PCAL_EX2:

• pico 1 (path 1 yaw): +150 steps
• pico 2 (path 1 pitch): (not touch)
• pico 3 (path 2 yaw): +50
• pico 4 (path 2 pitch): +100

The following EPICS parameters were updated to reflect the updated beam position:

K1:CAL-PCAL_EX_TCAM_PATH{1,2}_{X,Y}

Also, the picomotor related paramters changed:

K1:PICO-PCAL_EX2_{1,2,3,4}_TARGET_POSITION

No significant change was observed on the RxPD after the adjustment.
Also we checked that the positions on RxPD are good.

TCam Images Before/After adjustment are attached.
