Summary
 
Observation code : VS05Z1    AIPS Version : 31DEC03   
Date of Observation : 2002/184    Difmap Version : 2.4a 
Source Name : J1118-4634    vsop_difmap used : No 
Calibration Source(s) : J1058-80         
Ground telescopes : HH HO  Model Fitted to data : Yes 
Tracking Station(s) : UZ    Image made : No 
Correlator : Penticton         

 
Abstract
FLAGV=-1; DQA reports no sat fringes and no GRT pre 10:05 Previous observations implied that the source resolves on space baselines. This limited (1.5 GRTs) experiment confirms that. Or one of the GRTs was off source. Harts reports pointing errors, but that is not conclusive.
