Daniel's "posted without comment" .pdf reveals a couple of weird things that may incline some to say things like "oh! there's a change there! What's that jump? Doesn't it now look like it's turning up like the other chains?" Don't get caught up in that game. This is the game we've said we'll be playing for weeks. The test mass has still only displaced 5 [um] at most. We need to go more than 100 [um]. Further -- the test mass is *still not free*. I attach transfer functions taken just after this trend was posted. It's still frozen, the TFs look the same as the have since we first started measuring in this year (see LHO aLOG 15878).
