Abstract No space fringes are detected by Penticton correlator and analyst. SH has ground fringe with only IF1. KA behaves very strange with low signal to noise at the first three hours and with firm signal only at the last two hours. Fringe delay and rate of KA looks continuous in the entire run, but with more scattering during the former weaker part. The averaged visibility amplitude of KA baseline results in beating in strange manner and generally much weaker value than expected value, as seen in many other experiments around this period. MP-SH baseline have 1.0 Jy at 110 M lambda, which is very much consistent with PLS result that indicates 0.8 Jy at 120 M lambda. However KA-SH baseline has only 0.4 Jy in maximum at 25 M lambda while PLS was showing 4.5 Jy at 5 M lambda. The calibrator 1334-127 was observed by SH and MP with visibility amplitude 2.1 Jy at 113 M lambda, while PLS results showed 5.0 Jy at 120 M lambda. The ATCA monitor indicated that this source decreased the total flux from 4 Jy in 1996 to 3.4 Jy in Dec.97. The information to correct GRT amplitude is not sufficient, hence no image was created. The space baseline exists only at more than 200 M lambda but I suspect that space fringe could have been detected marginally. I would suggest that this experiment is to be re-scheduled, but not with very high priority. This is one of several sources which are not in 'complete sample'.
