- After finding a new alignment this afternoon, we realigned the DIFF beat note.
- We halfway succeeded in scripting the CARM TR transition. The setup is now all done in the state "CARM_ON_TR".
- The actual transition requires an ezcaservo (to suppress the voltage difference on the CM board while ramping).
  We struggled to implement it in Guardian. For now the following lines are required:

ezcaservo -r H1:LSC-REFLBIAS_OUTPUT -g 0.000003 -f 1 H1:ALS-C_COMM_VCO_TUNEOFS -t 120 &
sleep 5
ezcastep H1:LSC-REFL_SERVO_IN2GAIN -s '0.25' '+-1,28'
ezcawrite H1:LSC-REFL_SERVO_IN2EN 0
ezcaswitch H1:LSC-REFLBIAS FM5 FM8 ON

The last step engages a boost and a lead filter.
Attached below is a loop transfer function of the CARM loop at sqrt(TRX+TRY)=1.5.

- After that we moved the arm powers to sqrt(TRX+TRY)=1.5 (about 200nm). There we handed off to H1:LSC-ASAIR_A_RF45_Q.
- This took a input matrix gain of 4e-7. We saw an oscillation kick in at 20 Hz, se next we will try at 2e-7.
