Summary
 
Observation code : VS11G    AIPS Version : 31DEC05   
Date of Observation : 1999/139    Difmap Version : 2.3c 
Source Name : J1014+23    vsop_difmap used : Yes 
Calibration Source(s) : 1253-055         
Ground telescopes : MP, HO, KA, SH  Model Fitted to data : Yes 
Tracking Station(s) : RZ    Image made : Yes 
Correlator : Mitaka         

 
Abstract
No fringes detect for VSOP. Ground telescope gains are terrible. Determined in adhoc manner. But, also used global fringe fit. Ground resolution image is probably okay, slightly resolved. VSOP spacings long. Non-detection is reasonable.

Comments on Difmap processing
Space baselines not detected. However, a non-detection is not unreasonable.
