Summary
 
Observation code : VS06z    AIPS Version : 31DEC00 
Date of Observation : 1999/229    Difmap Version : 2.4a 
Source Name : J0149+0555    vsop_difmap used : No 
Calibration Source(s) :          
Ground telescopes : MOP  Model Fitted to data : No 
Tracking Station(s) : NZ    Image made : No 
Correlator : Penticton         

 
Abstract
Experiment correlated in Dec-1999, so requires a sqrt(2) correction due to correlation coefficient scaling factor error. So total required correction is sqrt(sqrt(2)) = 1.1892

Comments on Difmap processing
Only a dingle baseline so no model fitting or imaging attempted. Visibilities from 250 to 450 Ml show no significan variation in amplitude with a mean flux of ~0.4 Jy.
