We changed the refl air phases to the values measured here 45791 This change was made around 7:15 UTC December 12th. The first time we locked DRMI with these settings it took about 3 minutes after making the change. The second time was just over 10 minutes. While it doesn't seem obviously better or worse, I would like to try leaving these phases in for a day or so to look at the DRMI locking times.
PRMI would only stay locked for a few seconds after these new phase changes, seismic is pretty high at the moment though. DRMI still locked ok with this phasing.
