Does not look like an IMC/PSL lockloss; trends attached. The NPRO temp has been glitching this morning, not drastically, which has been causing the EOM drive to be higher in general, but these glitches were not happening at the time of this lockloss. The shape of of the signal on AS_A is indicative of an arms lockloss and happens before the IMC loses lock according to MC2_TRANS. Additionally, the lockloss tool shows glitches on ETMX starting up to second before the lockloss, although the ETM_GLITCH tag was not applied in this case as the glitches did not meet the required threshold.

(The ndscope template I'm using lives in my home directory ~/templates/psl_glitch_hunting.yaml)
