Followed setup instructions from 80010, last done in 86445. Increased to 75mW injected in the SEED beam, we had 1mW on OPO_IR_PD_DC. Have counts of ~60 and 66 on ASC-AS_A and B and 7e-4 on ASC-OMC-A and B NSUMs all similar to the August 19th measurement. To turn on the OMC ASC, H1:OMC-ASC_MASTERGAIN to 0.02. Took H1:OMC-PZT2_OFFSET goes down to -50 to start and then ran a template /sqz/h1/Templates/dtt/OMC_SCANS/ Sept16_2025_PSAMS_OMC_scan_coldOM2.xml ref 35,36.
PSAMS settings at nominal ZM4/ZM5 6.0V / -0/4V. Measured mode mismatch of TEM02 of 2.975%. In August 86445, this was only 2.174% however in that measurement, the OMC ASC has been left off so there would have been more in the misalignment peaks.
