Between yesterday 2024/04/17 16:48utc and today's lockloss at 2024/04/18 15:25utc, there were three sets of times where the calibration kappa values were suddenly louder than normal. Attachment1 and attachment2 show the three lock stretches (labeled 1, 2, and 3) over which this was seen, as well as showing kappa ranges from other locked times. The white dotted lines give an idea of the boundaries that the majority of kappa values fall within. The first time this showed up was 2024/04/17 16:48utc(stretch1), where we were locked in NOMINAL_LOW_NOISE and commissioning. The kappa values had flatlined for three minutes before then coming back larger than normal. Stretch2 and stretch3 were over the entirety of the next two locks. However, the lock following those two starting at 2024/04/18 17:26utc, the values seemed to be back to normal. 
I mentioned this increase to Louis last night and he said "I think we need to increase the calibration line amplitudes". I'm not sure if something was done about this today between locks that brought the values back to what they were previously.
