I've wrote a small script to revert ZM sliders after a SCAN_ALIGNMENT is run (SQZ_MANAGER state 105) incase we don't like it. It does a rough search for when this state was last run in the past day (it probably can be reduced but I needed a larger range for testing) using minute trends. From this time it then does a more narrow second trend to get more accurate state boundary times (did this for speed of nds2 calls), then it just takes the slider values of ZM{4,6} from a minute before the most recent SCAN_ALIGNMENT started and caputs them.

You can change the lookback time by changing the "days" and "hours" variables at the top of the script which lives at /opt/rtcds/userapps/release/sqz/h1/scripts/revert_sqz_align.py
