Abstract Good fringes were found to Halca as well as ground antennas. Amplitude self-calibration was not carried out since there was no co-observing time for all 4 stations. As a result, imaging was done with phase self-calibration only. A three Gaussian components model was used to fit the calibrated data. Calibrator (1334-127) was only detected on one ground baseline (HartRAO -- Mop) of 9,000km with a correlated flux density of 0.75Jy, too low compared to the PLS results of 5.0Jy at 7,200km.
