Next to the big red button, there are 4 new red/green lights with 2 readouts that show the outputs of the nominal and earthquake sensor corrections for each test mass. The idea is that if there is an incoming earthquake, the user will look at the lights and if any of them are red, wait for them to go green again before doing the transition to the earthquake mode, or before going back to Windy. 

The transition to the earthquake seismic state has occasionally caused locklosses. I haven't been able to run down the exact cause for this but, it could be from some low frequency offsets in the different sensor correction paths. These offsets are caused by the different filters and sensor configurations used by the nominal and earthquake sensor correction paths. I've added some lights and readouts to hopefully make the transition smoother. These are the red and green boxes in the upper left corner of the attached screen shot.

The boxes for each chamber are green when the differences between the two paths are less than 3 microns and they go red when the differences are greater than 3 microns. I don't know for sure if 3 microns is a good limit or not, but I've watched successful transitions that were about the level. 

In the attached screen shot, the yarm chambers have are red because they have offsets of about 8 microns. The units in readouts are nm, i.e. for the top right box the difference between upper number and lower number is (-309) - (-8196) =7887 > 3000. The bottom two boxes are green, i.e. for the bottom left box the difference is 37-787=750 < 3000.
