BS, ITMX cameras frozen

We were kicked out of observing due to the BS camera not updating and the camera servo going back onto ADS. The ITMX camera also seems to be reading only 0's. Dave is currently working to fix this.

Happened on Nov 11 - alog74160 and Oct 25 - alog73749

BS camera (h1cam26) is back online. I had to power cycle the camera via sw-lvea-aux POE port off/on sequence and then restart the camera process on h1digivideo2.

H1 is back in observe.

Plot shows second trends from 00:40 to 01:35 PST this morning. The top trace (blue) is BS cam x-centroid, the middle trace (green) is H1-range and the lower trace (orange) is H1-observe-bit with x100 gain.

H1 kept a good range throughout apart from a momentary drop to 20MPc.

H1 came back to observe within a few minutes of BS camera image restoration.
