Abstract
This is with only two GRTs experiment. Good signal for Space baseline realized up to 500 M lambda. The short spacing is KA-MP at 95 M lambda with 0.4 Jy in visibility. The PLS result is about consistent with 0.5 Jy at 120 M lambda. There is no USNO map or 15 GHz survey result available for this source. The calibrator 0420-014 has 0.9 Jy at 112 M lmabda, while PLS got 2.5 Jy at 120 M lambda.
