Abstract
HO did not observe the fringe finder. No space fringes. Very hard to say more. A Gaussian fit was made.

Comments on Difmap processing
A Gaussian model with a peak of 0.15 and a major axis of 0.3 fits the data. It is an ICRF source, but the USNO web page is down. No mention of structure in the Ma paper.
