High SNR fringes found near -680 µm but PAVO had difficulty locking on them; tried adjusting dtime, autosearch, SNOFF/SNON parameters which seemed to improve things, but the fringes kept passing by. Also had difficulty keeping north on the PAVO camera; the north servo kept locking on noise and drifting away.
