Print this reportMICH noise budget : Summary of main contributionI summarized the (my selected) main noise contribution to MICH noise budget. We measured planned TF for MICH, the analysis will be performed offline.
After the oplev centering work in IY (klog30102), the spectrum of IY control noise changed, so I measured again for TM Y angular control noise (Fig.1. )
Fig.2. showed the current MICH noise budget in online.
Then I requested IY to LOCK ACQUISITION state, noise bugdet changed to Fig.3. (Mainly the 7.5 Hz disappeared.), spectrum comparison in Fig.4.
