Sheila and Matt found that we get different temperature optimizations when optimizing the SEED beam or the RF6 with OPO locked. We tested this out again by checking the NLG again before and after using Sheila's new 85532 SCAN_OPOTEMP OPO GRD state, with a silightly increased range (0.015 rather than 0.01 and 180s rather than 120s), see plot in exports/SQZ/GRD/OPOTEMP_SCAN/. It adjusted temp -0.002deg, the NLG did not change, stayed at ~11.8.
I ran a script that pulls the full 524 kHz OMC DCPD A and B channels during the no squeezing time. The data that was saved was 10 minutes of no squeezing data. I saved the data into .gwf files at the full rate, and another downsampled to 64 kHz.
The data is saved in /ligo/home/elenna.capote/OMC_DCPD/251007-102149_xcorr_data as OMC_DCPD_{A,B}_{524,64}.gwf which can be easily read by gwpy. Unfortunately I can't upload them here because the alog doesn't accept this file format, but I can pass it along to you as necessary if you don't have control room access.
