ETMx sag status - post vent fix

So far so good.  Attached is a plot of the EndX station temp (degC), pressure (torr), and suspension vertical sags (um).  We're only at ~20Torr and falling but the suspensions in this chamber look to be sagging by the expected amount.  No sharp changes in the shift to indicate poor health.  The temp change that John made yesterday seems to be stabilized.  We'll run TFs on the ETMx after the buoyancy effect has stabilized (almost complete now as shown in the ~100um drift down on the sus V trends, but we'll wait a bit longer to be sure).
