The TCSY rotation stage was cycling through adjusting power, so I did the usual fix of slightly tweaking the calibration. I changed the power in value from 3.8W to 3.75W 3.65W. One day we will need to get the calibration correct with a full search with this rotation stage.
In SDF there the H1:TCS-TCSY_LASERPOWER_COMMAND channel was flickering as the rot. stage was rerequesting to change powers. I unmonitored this channel.
EDIT: spoke too soon, changed to 3.65W.
