Today during commissioning at 16:29:41 UTC I ran the SCAN_SQZANG_FDS guardian state and it changed the squeeze angle from 170.94 degrees to 163.08 degrees.

Then Camilla and I changed the filter cavity detuning from the nominal value of -32 Hz, measured DARM between 20 to 30 Hz atr each step. This was following this entry by Vicky and Camilla. The lowest value we tried was -44 Hz and the highest was -26 Hz. The optimal seemed to be between -38 Hz and -32 Hz, eventually we chose -36 Hz as it was better 30 and 46 Hz, and among the best between 60 and 70 Hz. Above 70 Hz it is hard to see the difference between traces.

We accepted the new value for H1:IOP-LSC0_RLF_FREQ_OFS in the OBSERVE.snap file in sdf.
