Summary
 
Observation code : VS04F    AIPS Version : 31DEC03 
Date of Observation : 1999/117    Difmap Version : 2.4a 
Source Name : J0745-00    vsop_difmap used : No 
Calibration Source(s) :          
Ground telescopes : HH TR  Model Fitted to data : No 
Tracking Station(s) : RZ NZ    Image made : No 
Correlator : Penticton         

 
Abstract
No HALCA fringes, even tho the baselines are shorter than the earth baselines. Single baseline flux measurement at 130 Ml 0.17 Jy, in line with the pre launch

VS04F2 showed signs of space fringes, so I think it is a failure.

Repeat.
