Summary
 
Observation code : VS11W1    AIPS Version : 31DEC03   
Date of Observation : 2002/254    Difmap Version : 2.4a 
Source Name : J0509+0541    vsop_difmap used : No 
Calibration Source(s) : J0423-01         
Ground telescopes : MP HO KA SH  Model Fitted to data : Yes 
Tracking Station(s) : UZ    Image made : Yes 
Correlator : penticton         

 
Abstract
The flag table needs removing. No fringes to VSOP. Penticton reports Morpa-VSOP fringes for one 1 IF. These seem to be a furfy. The resolving GRT baselines are in line with no VSOP fringes.
