Print this reportComment to Violin modes moving (31594)Cooling of radiation shields started on 16 December (klog 32011, 32013, 32014). The IM stage of each suspensions are currently cooling at a rate of approximately 9 degrees per day. I noticed that the peak shift of the violin mode due to this is also visible in the median spectrogram on SummaryPage. In the 1st, 2nd, and 3rd violin mode frequency bands, a peak shift is visible at the frequencies where the violin mode is supposed to be present.
