Summary
 
Observation code : VS04h    AIPS Version : 31DEC00 
Date of Observation : 1998/32    Difmap Version : 2.4a 
Source Name : J1218-4600    vsop_difmap used : No 
Calibration Source(s) : 1424-418         
Ground telescopes : HH, MP  Model Fitted to data : No 
Tracking Station(s) : TZ, GZ    Image made : No 
Correlator : Penticton         

 
Abstract
No fringes detected to J1218-4600. Ground fringes were seen on the fringe-finder, 1424-418, so no reason to expect GRT problems. 1424-418 was found to have a flux of 1.3 Jy on the Mopra-Hart baseline (160 Ml).

 From DQA it looks like delays might be very large if there are any fringes at all. A look at the ground baseline with POSSM suggests a non-detection.
