Trended IM1-4 (HAUX) inmons to look for any drifts - looks fine

Betsy, TJ, Rahul

This afternoon I trended the inmons of IM1-4 to look for any signs of suspension drifting after they (IM1-2) were moved (and then reverted to nominal) this Tuesday (LHO alog 77347). Attached below is the ndscope plot for the last 2 weeks and they look fine to me (IM1 LR and UL bosems showed movement but that was 12 days ago - possibly slider changes - see J Kissel's alog 77211).

I also took their osem spectra and they look fine.
