We tried the PSAMS coarse scan from 0 to 200 with 100 step for two PSAMS. So 9 PSAMS setting in total. The nominal PSAMS is 100/100 and we tried 0/0. Unfortunately, when we tried 100/0, the lockloss happened. For each PSAMS setting, we ran the SCAN_ALIGNMENT with asqz-optimized and took 5+5 minutes quiet sqz/asqz data. The attachment shows the result. The 0/0 has much worse anti squeezing and large frequency dependence compared to 100/100. However, we are not sure if the mode matching is really worse or alignment is bad with 0/0 although we ran SCAN_ALIGNMENT. We will try to compensate the ZM alignment change caused by PSAMS change tomorrow.
