Summary
 
Observation code : VS06X    AIPS Version : 31DEC03   
Date of Observation : 2001/337    Difmap Version : 2.3c 
Source Name : J1058+19    vsop_difmap used : Yes 
Calibration Source(s) : J1159+29         
Ground telescopes : Kal Mop  Model Fitted to data : Yes 
Tracking Station(s) : ?    Image made : No 
Correlator : Penticton         

 
Abstract
Single weak ground baseline ~ 50 mJy. No VSOP fringes - as would be expected. Looks reasonable given the SEFD and the correlation. J1159+29 is 0.8 Jy.
