Progress on Suspension Health Checks Post-Pump-Down
J. Kissel

I'm slowly working through measuring the standard health-check transfer functions and ASDs for all suspensions now that most chambers are closed and pumped down. I'm seeing a few suspicious things along the way that I'll need to go back and run more tests (see "notes" below), but for now I'm moving on when I see weird things, trying to get all that are "OK to GO" measured and confirmed good. I list the progress below. Where there are suspensions that are "OK to GO" I list the date of the measurement.
