Summary
 
Observation code : VS05a    AIPS Version : 15OCT99   
Date of Observation : 1998/11    Difmap Version : 2.3c 
Source Name : J1215-17    vsop_difmap used : Yes 
Calibration Source(s) : 1334-127         
Ground telescopes : HA, NO, GB  Model Fitted to data : Yes

Abstract
Good fringes for all baselines. GB has strange amplitude drops frequently, which were carefuly flagged later in difmap.
