J. Kissel,

Now that
    - Hugh unlocked H1 EY's HEPI, and brought the seismic isolation system to nominal performance (LHO aLOG 41392), and
    - The vacuum team's got BSC9 to ~1e-6 Torr
I wanted to confirm that we could align to the optical lever (our best alignment reference until we get the arms back). 

We can!

This means we can begin on the long list of "Does It Work?" measurements in chamber:
    - Standard suite of spectra and transfer functions of OSEMs (on both QUAD chains and TMSY)
    - Finding the new highest Vertical and Roll modes
    - Measuring their Q to confirm that the new BRDs are functioning as expected (a la LHO aLOG 40098)
    - Turn on high voltage, measure the ESD effective bias voltage
