Abstract
One of five survey datasets I am reducing that have only two GRT's, to determine if they are useful or require re-observation, following the July 1999 Survey Working Group meeting at ISAS. Fringes between Mopra and Hart and the last timerange between Mopra and HALCA on the shortest projected baselines ** I recommend that this observation be re-scheduled with medium priority since the source is strong enough to be detected on at least some space baselines, should do better with three GRRT experiment **.

Had tape reading problem with Penticton tapes - asci junk before FITS header. No VPLOT done. Scan breaks for INDXR not used.

CALIB was not run after final fringe-fit, so preliminary fringe-fit plots represent the final delay and rate solutions that were applied to the data.
