PRMI ASC feedback on PRM hasn't been successfully used since the vent. The operators have been by hand touching up PRM.
We looked at this data for PIT (attached today plot) and YAW (attached yesterday plot). Using the same sensor, REFL_A_RF9_I, is fine, zero crossings of signals are good. The YAW sign is wrong. Have changed the gain in ISC_DRMI.py for ASC-PRC1_Y_GAIN from -0.1 to +0.1 and reloaded. It will get set back to zero by the guardian so shouldn't effect anything else.
This is untested and left off: to test you would need to change line155 of /isc/h1/guardian/lscparams.py to set PRMI ASC to True.

We tested these before turning on, YAW worked great, PIT did not, see attached error signal not coming to zero as alignment is improved. Unsure what has changed but Elenna and Sheila saw similar weirdness in PRX this AM. Can try again next week.
