Summary
 
Observation code : VS06u    AIPS Version : 15OCT99   
Date of Observation : 1999/145    Difmap Version : 2.3c 
Source Name : J1257-3155    vsop_difmap used : Yes 
Calibration Source(s) : 1255-316         
Ground telescopes : HO, SH, HA  Model Fitted to data : Yes 
Tracking Station(s) : UZ, RZ    Image made : Yes 
Correlator : Penticton         

 
Abstract
Data was correlated in non-standard mode with 64 channels. Space fringes are detected from RZ. The UZ might have problem. Due to unkown reason all baselines show remakably low amplitude and hence, derived factors are multiplied in AIPS.
