ASC sensing matrix measurement

[Vaishali, Jenne]

We used the last few minutes of commissioning time today to measure the ASC sensing matrix. This is the first time that we have made this measurement since POPX was installed. Per JeffK's suggestion, we turned off the 7.9Hz calibration line to avoid confusion with our 8.125Hz measurement frequency (we used his new guardian state that actually turns off all the Pcal lines, then turns them back on before we go to NLN).

Vaishali is looking at this data to compare with previous measurements, and her Finesse model.

Recall that in the table below, elements that are grayed out have lower coherence.

Today we used the commissioning window to re-measure the ASC sensing matrix for Pitch and the results show that the values for the individual DoFs hasn't changed by too much. We will now make radar plot comparisons of the same and compare them to alog 26023 .

We are trying to figure out why the measurements look different compared to 26023 .
