IMC_IN power change from 2W to 10.3W:

• IO GigE 2, CAM29_Y,  IMC_IN: beam centroid moves from 234 to 227 pixel location, delta = 7
• IM4 Trans YAW: beam moves from 0.852 to 0.879 (0.005 changes are significant on this QPD), delta = 0.027
• POP_A PITCH:    0.425 to 0.77, delta = 0.345
• POP_A YAW:      -0.63 to -0.93, delta =-0.3
• POP_B PITCH:     0.6   to  0.9, delta   = 0.3
• POP_B YAW:      -0.75 to -0.9, delta =  -1.5

My unverified calculation from the GigE camera centroid change would result in a change of 1.5mm at MC2 (based on 5.6um pixels, and distances of 0.508m to the camera, and 20m to MC2).

The IMC WFS output for MC1 and MC2 see the beam change, but are slow to react, but clearly see it.
