| Abstract
No space fringes are detected by Penticton and analist. Kashima shows remarkably low amplitude. From the cross points analysis the factor 4 was multiplied with Kashima amplitude. Grobal amplitude self-cal was performed for ground baselines and final amplitude is 0.5 Jy at 180 M lambda of Ceduna-Noto baselines. This observation should be re-schedule if there is any chance. |

| Comments on Difmap processing
From the cross points analysis in difmap a rough factor 4 was derived for Kashima amplitude. Grobal amplitude self-cal was performed for ground baselines including CD, KA, NT, HA. !
