We found the ITF in CARM 0

we started to characterize the config. 160Hz of DCP (including the OS it comes from 190Hz).

the BS has been engaged with phi0 = 1.35 for both.

Aligning the SR vs 112MHz we could not improve the DCP.

We have remeasured the DCP and tuned the LSC_MONI.DARM_HF_LINE_PHI_SET from 0.6 to 0.46 to find the same value. We need to understand if the LSC_DARM_DCP_TEST_FREQ is reasonable or not.

10:05 LT DAS tuning done (Alessio will add more details)

the 56MHz sidebands shape are improved @ CARM0 (not anymore the vertical structure on LSB 56MHz), see Figure 1 and 2 CITF yesterday and today, 3 and 4 Carm 0 yesterday and today.

We've aligned increasing the pole from 190 to 297Hz of DCP  (measured with DARM noise @12:43UTC and the Michal script see Figure 5). The online channel instead is not working (just ingnore the channel at the moment).

In Figure 6 it is visibel that the B1p_QD1_V_50MHz_Q is well sensing the BS (with pi/2 of optimal phase). I changed then the phase in the ini file from 1.35 to -0.22 (to be checked tomorrow, it could be a pi of difference).
