This morning we saw a few RA fluctuations happening a period intervals.  Visible inspections of the gear train showed no obvious issues even while the RA showed jumps.  I expected to see some motion on the spur gear or jumping of the worm gear nothing was seen.

 Adding a 4 pound weight on the t-handle seems to have cleared up the jumps.  This is the same mass on a string that we historically used to quell RA issues.

KCOR COMMENT BY berkey: Wed Aug 19 23:14:53 GMT 2026
Kcor realtime software updated to collect camera temperatures for every fits file.  After some testing it looks like the current scheme works effectively without getting into race conditions with other camera operations.

The infrastructure to add the 4 temperature values into the header were built up.  However during testing we found that that adding all for new header keywords put us over the 2-36 header card block that we allocated in the Kcor data.  We can accommodate 2 new  header values one from each camera.   
Going froward we need to chose one of the following:
   - Only save the Camera array temps and not the case temperature. 
   -Change socketcam of the labview header injection code to make room for 3 -2880 byte blocks unsteady of the 2 we currently allocate.
  -Remove to other keywords or comments from the L0 header.

For now the header code has been revert no not record the camera temps until we pick a path
