JAC WFS A and B whitening off for six days

Jennie W, Ryan C,

 

Ryan noticed that DIAG_MAIN was complaining about the anti-whitening and whitening filters for the two JAC WFS not matching. The fix was to go on sitemap->JAC OVERVIEW NEW->WFS->WFSA/WFSB->I Filters screen and toggle the switch for STAGE 1 on and off and on.

The CS_ISC model shows we expect the first stage of whitening to be on.

I trended back and it looks like the all four filters were switched off on 16th Sept at 11:04:26 UTC and then just the anit-whitening filters were switched on 6 hours later.

After we reset the whitening filters we checked there were no diffs on ASCIMC, CS_IMC and that the messages on diag_main had gone.
