MICH : (Fig.2.) We need to tune the gain, I added the +3.49 dB to MICH2 FM1, then OLTF became similar as shown in Fig.3.
PRCL : (Fig.4.) We need to tune the gain, I added the +2.23 dB to PRCL1 FM2, then OLTF became similar as shown in Fig.5.
CARM : Ushiba-san may report later, we changed the IFO_REFL_HWP final value, the OLTF changed from yesterday as shown in Fig.6.
from the klog32642, that peak may be the violin mode of the ETMX
pink (11:00)
green (11:10)
blue (11:20)
red (11:30)
I added the notch filters at FM3 of ETMX_TM_LOCK_L filter bank as shown in fig1.
After engaging notch filter, the peak height starts to decrease, so the notch filter seems to work well.
I also modified the guardian so that the FM3 is engaged after locking PRFPMI with DC readout (fig2).
In addition, I changed DOWN state so that the FM3 is turned off when the lockloss happens (fig3).
