This morning, since the ITF unlocks once the SSFS is engaged, we checked the longitudinal and angular working points of the IMC loop.

• For the longitudinal we found that the offset which minimize the coupling of the fmoderr line on the pmc is -0.07 V (instead of 0.03 V, so no much difference), see attached plot.
• For the angular wp  (offsets on the galvos used to center the beam on the RF quadrants), we found that the did not change substantially:

ACL_CONST_CH FF_H_offset    "V/V"    1   LOOP_FREQ   -0.25 #-0.28
ACL_CONST_CH FF_V_offset    "V/V"    1    LOOP_FREQ   +0.5 #+0.58  
ACL_CONST_CH NF_H_offset    "V/V"    1   LOOP_FREQ   0.0 #-0.04  
ACL_CONST_CH NF_V_offset    "V/V"    1    LOOP_FREQ   -0.19 #-0.19 

• IMC UGF seems to be ok (around 101 kHz with 25deg phase margin)
