Summary
 
Observation code : VS10P1    AIPS Version : 31DEC03   
Date of Observation : 2002/137    Difmap Version : 2.4a 
Source Name : J2239-57    vsop_difmap used : No 
Calibration Source(s) : J0303-62         
Ground telescopes : HH HO  Model Fitted to data : Yes 
Tracking Station(s) : UZ    Image made : No 
Correlator : Penticton         

 
Abstract
No space fringes. This source has a SUMMS position and a constant (0.7) flux at ATCA. The flux between HH-HO is ~ 0.3 Jy. A 0.7 mas source is consistent.

Comments on Difmap processing
No much can be said, but I assumed that the ATCA flux was constant, that the source was simple, and fitted a point Gaussian to the data.
