Summary
 
Observation code : VS03X1    AIPS Version : 31DEC03 
Date of Observation : 2003/21    Difmap Version : 2.4a 
Source Name : J1357+19    vsop_difmap used : No 
Calibration Source(s) : J1430+10, J1405+04         
Ground telescopes : MP HO KA SH  Model Fitted to data : No 
Tracking Station(s) : UZ    Image made : No 
Correlator : Penticton         

 
Abstract
No space nor Kashima fringes. Mopra fluxes seem very low -- also true for the cals.

A failure.

Comments on Difmap processing
Something is wrong with the data. Kashima/VSOP have no fringes. Mopra seems to be low (or Shanghai is high). I think the former from comparison to the PLS model. Can't gscal with only 3 telescopes.
