Attachment 1 - Unsqueezed (left) vs. squeezed (right) DARMs in ER16, with respect to O4a. Like Gabriele's plots, the ratios on the bottom show a given trace / O4a reference, so ratio > 1 means more noise now than O4a.
Colors: Rainbow colors are ordered past to present: e.g. Red = O4a, ... Purple = now.
Attachment 2 - SQZ dBs after subtracting non-quantum noise, with various recent PSAMS settings. Upper subplot: Anti-SQZ, Lower subplot: SQZ. Lines are a moving average of the data. Some caveats for the subtraction: here I am using the same H1 unsqueezed quantum noise model for all subtractions; this may not be the most accurate, but I think it should be fairly close.
Reference alogs wth times that I used to grab GDS_STRAIN_CLEAN:
Adding FDS times from the DARM comparison in 76955, and only including times with sqz/no-sqz comparable to those recent darm comparisons.

Attachment 2 - SQZ dBs after subtracting non-quantum noise. Analysis with non-quantum noise subtraction for this week's PSAMS data in 76925 and 76949 ongoing.
Attachment 3 - Comparison to a very basic gwinc noise model (pulled from H1 NB) for squeezed darm. For example the dashed purple "Unsqueezed QN model" is (almost) what I am using for subtracting non-quantum noises.
Colors are rainbow-ordered time-wise. Red = O4a reference. Purple = 4/4 times from 76955 for FDS DARM comparisons.
Note: here the PSAMS settings are referenced in terms of strain voltages. Just pointing out that LLO has a guardian to servo PSAMS voltage to meet the "_TARGET" strain gauge voltage LLO:63403.
