(Mitaka/Penticton/Socorro)} : Penticton {AIPS Version used (e.g 15OCT98)} : 15APR99 {Difmap Version used (e.g 2.3c)} : 2.3c {Was vsop_difmap used? (yes/no)} : yes {Abstract. Write a brief summary of the data reduction and its outcomes} : No space fringes can be detected. As a result, there was only one ground-baseline (Kashima-Mop) data for both survey source (J0407-12) and calibrator (0420-014). J0407-12 could be weak during the observations. However, the radio light curve data are not available. A re-observation is recommended. #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} : yes {Data quality reports and plots retrieved?
