Today after having reached LN3 (56MPc) we have aligned the SR (no offset on tx and ty). The transient is visible in the attached plot.

The sensitivity was quite low and worsened by the high CMRF. We re-engaged the BS ty loop but the required offset was too high to keep the lock.

data to be analyzed to evaluate the level of noise.

to be noted:

DC readout gain tuning (ITF_LOCK.ini)

#371 darm_gain_pd3 from 0.25 to 0.3

#383 darm_gain_b1_dc from 0.4 to 0.35
