After the spot move on July 31th, see alog 50954, the RF signal measured by REFL_A_RF45 has gone somewhat crazy. RF9 has increased as well, both in size and fluctuations, but still looks ok. This may be driven by alignment fluctuations, maybe caused by a TCS imbalance, or even related to the ITM point absorbers. Bottom line, the RF sidebands seem less stable in the PRC.
