After replacement of IMC CMS, we haven't tuned IMC CMS cmp gain and IN2 gain, I tuned them.

Since IMC CMS IN1 gain was changed from 16 to 4 due to the change of CMS, I reduced IN2 gain from 0 to -12 dB as shown in fig1.
In addition, to effectively activate ofs comp function, I set ofs comp gain of 3.358 at K1:IMC-SERVO_IN2GAIN_OFS_COMP_GAINNEG12_OFS.
Since the other gains are not tuned, I set a gain of zero for all the other gain setting (fig2).

After that, I measured OLTF of ALS_CARM (fig1).
UGF is around 2kHz, so it seems fine.
Then, I tuned the crossover frequency between MCL and laser frequency, which is now 100Hz (fig4).
For the adjustment, I added the gain of 1.5dB at FM1 of MCL filter bank as shown in fig5.

In addition, IMC CMS IN1 gain comp ofe was measured from +4dB to -20dB for the laser power up.
Same as IN2 comp offset, I set zero where I did not measure this time as shown in fig6.

I also adjusted the common offset (K1:IMC-SERVO_OFS_COM_CALI_OFFSET) so that IMC ASC feedback signals are not saturated.
The new value is 0.936.
