The OMC_LOCK guardian now has the states ADD_WHITENING and REMOVE_WHITENING, which do what they say on the tin. If you have one stage of whitening on, running ADD_WHITENING will turn on one more stage, etc.

They are not connected to the rest of the graph at all, so you'll have to run them manually.

They are intended to be compatible with full lock, so they can be run at any time (so long as you don't end up saturating the DCPD ADCs, of course).
