(Mitaka/Penticton/Socorro)} : Mitaka {AIPS Version used (e.g 15OCT98)} : 31DEC00 {Difmap Version used (e.g 2.3c)} : 2.4a {Was vsop_difmap used? (yes/no)} : yes {Abstract. Write a brief summary of the data reduction and its outcomes} : Just HO to VSOP. Very weak signal. A single value for the delay is used, and then a delay search. This will cause some signal loss. Data calibrated with both IF's tied in AIPS to improve signal. Very complicated source, so only VSOP baselines here. Core may be slightly resolved. #--------------------------------------------------------------------------- # Section 2 : Pre-AIPS Checklist #--------------------------------------------------------------------------- {PI letter retrieved (yes/no)} : yes {Data quality reports and plots retrieved?
