Centered IMC WFS

The IMC_LOCK node has been notifying of the IMC WFS not being centered for some number of days. While we were waiting for a small earthquake to roll through, I centered the WFS with a reminder from Sheila's alog54340. Steps were:

  1. Offload the MCWFS via IMC_LOCK
  2. Bring IMC_LOCK to OFFLINE
  3. Use the handy ndscope template on the IMC screen and the picos to center the signal on the WFS
  4. Accept any SDF diffs, these were in IMCASC from the MCWFS offloading (attach 1)

A screenshot of the final ndscope showing the movement is attach 2.
