Attached are plots of the IOO IMs, IM1-4, and their alignments in pitch and yaw.  Also plots of IM4 Trans pitch and yaw over 90 days.

Plot 1: IM4 Trans pitch and yaw

• - noteable is that at the start of the plot (sept 2nd) the pitch and yaw values were -0.2 and 0.054 respectively
• - change around sept 12th attributed to IM alignment changes, pitch and yaw now -0.330 and 0.095 respectively
• - mostly stable until oct 21st and by oct 29th pitch and yaw have drifted to -0.450 and 0.090 respectively
• - more drift and a change around nov 30th, and current values are -0.486 and 0.065 respectively

Plot 2: IM4 Trans and IM1-4 pitch

• - IM1 pitch changes are 10urad and smaller
• - IM2 pitch changes are 70urad and smaler
• - IM3 pitch changes are 12urad and smaller
• - IM4 folllows

Plot 3: IM4 Trans and IM1-4 pitch

• - IM1 yaw changes are 30urad and smaller
• - IM2 yaw changes are 5urad and smaler
• - IM3 yaw changes are 52urad and smaller - note, the big change near the end of the plot is due to an intentional alignment change
• - IM4 folllows

In all plots, changes can be attributed to both alignment shifts after shaking (HAM2 ISI trips / earthquakes) and intentional alignment adjustments.
