Abstract
This is one of extractions from Horiuchi et al. GOT w327d toward NRAO150, which is not in complete sample. There is no obvious space-fringes probably because the source is too resolved. The space baseline is all longer than 300 Mlambda. The source must have extended secondary componend toward NE direction but I can not see this even from GRT only data. Because GRT only data is poorer than PLS, all space data was retained for demonstration here in the result file. From radplot it seems resonable to detect no fringes at this longer baselines. Re-observing with shorter spacing with Halca will help to confirm this, but priority is not high.
