J. Kissel, J. Warner, D. Barker In order to close out ECR E1400295, WP 4987, and Integration Issue 921, I've removed the remaining old guardian infrastructure from the TMTS, HSTS, HTTS, OMCS and HAUX. This required updating the userapps/sus/common/models/ directory (which removes the guardian block from the common library parts for the OMCS and TMTS), and removing the guardian blocks myself from the HSTS_MASTER.mdl, MC_MASTER.mdl, RC_MASTER.mdl, h1sushtts.mdl, and h1susim.mdl. Once removed, I recompiled, reinstalled, restarted, restored all affected models (basically, every suspension but the QUADs, BS, and P/SR3), and had Jim and Dave help me restore the SEI system and perform a DAQ restart, respectively. All common and site-specific model changes have been committed to the userapps repo. All old guardian infrastructure has already been removed from the MEDM overview screens EXCEPT for the HSSS, i.e. the RMs, OMs, and IMs. I'll leave that for another day, but that should be that last thing LHO needs to do for this ECR, and it should require no more front-end code updates and/or code restarts. Note all new safe.snaps have been captured for the affected SUS *before* the computer restarts. I'd confirmed that all *corner station* cavities (via camera views) are well aligned. I did *not* reaffirm the Y arm cavity, and of course this bit me. Sheila had changed the gain for the H1 SUS TMSY OPTICALIGN Pitch to be negative (see LHO aLOG 14161), but never captured a safe.snap for it. For some reason, bringing the TMS to SAFE via guardian reverted the gain to positive, flipping the sign of the alignment offset, which distorted the green / red beam pointing into / out of the cavity. We've since fixed the sign, then captured and commit a new safe. Subsequently *all* new safe.snaps have been committed.
