With the OMC locked on a singel bounce beam and 10W of input power, I started a slow scan of the IMC VCO using a script that Anamaria sent. The scan started at 1212469399, or 10:03 local time. The script is set to run for 12 hours.
If anyone needs to stop it the matlab session that is open on ZOTWS11 (front corner next to Hugh) is scanning the VCO.
This is for a comparison to the measurements in LLO log 39247
The scan started at 5:02:56 utc and ended at 11:35:36 utc when the OMC lost lock (don't know why). The VCO frequency was swept from 78.62 to 79.33 MHz. That's a bit over half the scan, so I would suggest rerunning it some other time from 0 to 5 in the VCO_TUNEOFS channel (then it will take circa 6 hrs). I will start making the images for this part of the scan and post them on this alog later.
The IMC lock loss ended this scan. There was an oscillation in the FSS which may or may not have caused the IMC to unlock.
