| Abstract
Space fringes are detected from UZ tacking baseline. Ceduna has problem with no IF2 data. Kashima shows remarkably low amplitude. From the cross points analysis the factor 2.5 was multiplied with Kashima amplitude. However Kashima data was flagged for the imaging because of low signal to noise most of the time. |
