Tagging @DetChar and SEI for data in seismic's sensor correction configuration transition studies.

@DetChar -- the operators have been dilligently logging when they're transitioning from our nominal seismic sensor correction configuration to our earthquake configuration. Can y'all take a look at these times thus far in O3 and make and quantitative statements about how the change in configuration impacts the IFO and the searches? Similar question about the actual *transition,* with an eye towards answering the question "do we need to take the IFO out of observation ready to make the switch, or can we treat it like violin mode damping?"

In order to facilitate this study, I'll take a moment to peruse past aLOGs and make sure DetChar and SEI have been tagged.

For longer term study, I've opened FRS Ticket 13123.
