The ground motion is just too high, so Evan, Travis and I agree that we should call it a night.  We can't hold DRMI for more than 2 minutes or so.  Earlier today, I flipped the phase of the ASAIR 90 PD, so that we get roughly the same number of counts when DRMI is locked as we used to.  We only use ASAIR90 for thresholding engagement of the DRMI ASC, so it's not a super critical PD phasing-wise.  I'll come back to it tomorrow.
