Sheila, Ryan S, Jennie, Jenne, Control Room...

Ryan started with green initial alignment and got PRX locked 69467.

Sheila  continued yesterdays work looking for signals in the REFL path. Could again get signal on ASC REFL B but not A. She measured PRX OLG, see attached, it's a bit below the reference.

Sheila reset the LSC POP A 45 dark offsets that are hard coded in ALIGN_IFO PREP XARM state.

Sheila set up some sine oscillations on PM1 and RM2 to try to find the beam on the POP diodes in HAM1. 

Jennie/e and I then reset IM1,2,3,4 to a November time 2025/11/16 15:34:24 UTC (ndscope on cdsws44 had some issues with this yesterday). And then we walked IM3 and IM4 to get IM4_TRANS and ASC-POP_A back to this time which was quite different IM3/4 alignments. ASC-POP_B ended up not too far off. Plot of now and November attached. In particular, IM3 and IM4 PIT OSEMs are 200 and 400urad different than November. 

Ryan and Jenne improved Xarm IR transmission via PR2.
