Last night after checking cabling and turning on ISS, we tried several times to handoff to REFL_DC but it didn't work at all.

Some issues:

1. The ISS was injecting a lot of very low frequency power fluctuations because of bad AC coupling.
2. The SR560 @ LSC rack was saturating a lot with the x10 gain that Jenne and Rana put in; we turned it back to G = 1.
3. The ISS was also saturating a lot. We turned it off around 4 AM, but still no success.
4. The ALS sequence for finding the Red Resonance takes too long (~2 minutes), so we're trying a faster scheme tonight.
