This morning we have finished to retune the phases for SR alignment

CARM null

SR tx ; error signal ASC_SR_TX_DCP_HF_B1p_I; measurement UTC 9 Oct 7:27 - 7:41 ; initial phase -0.31; new phase 0; Figure 1 

SR ty : error signal ASC_SR_TY_DCP_HF_B1p_I; measurement UTC 9 Oct 7:41 - 8:10 ; initial phase -1.47; new phase -1.2; Figure 2 

LN 2

SRtx : error signal ASC_SR_TX_DCP_HF_phi_B1_I; measurement UTC 8 Oct 8:42- 8:51 ; initial phase 2.2; new phase 3.8; Figure 3

SRty : error signal ASC_SR_TY_DCP_HF_phi_B1_I; measurement UTC 8 Oct 8:25- 8:41 ; initial phase -1.47; new phase -1.6; Figure 4

the phases have not been implemented yet

DCP calibration

the DCP calibration hase been done by injecting DARM broadband noise (ampl 20) and fitted by manuel for different alignment of SR

8:54:25 UTC (120sec ) DCP online = 375Hz DCP fitted = 345Hz

9:15:55 UTC (120sec) DCP online = 290Hz DCP fitted = 260Hz

9:31:55 UTC (120sec) DCP online = 200Hz DCP fitted = 178Hz
