Beam spot control is turned on
As shown in the attachment, I turned on the beam spot control. The flag of the beam spot control in sqzparams is set to True. The beam spot control seems working well, but I feel the yaw was too slow so I removed the -20dB gain (FM7 in INJ_ANG_Y). I will tune the green QPD offset with FC2 dither tomorrow.

I tuned the green QPD offset as shown in the attachment. The FC IR trans is 0.1 with -12dBm CLF6 now, but it was 0.1 with -26dBm CLF6 in O4a so it is better to align the IR trans PD.
