Editting: All Ka data was flagged...even though Ka FRING solns were obtained, Ka amps were very low when data was split. Lows amps were confirmed with UV-crossing points. A-priori Ka amp calibration was ok. Cleaning/Phase self-cal: Cleaned out central component, which turned out to be two very closely spaced components. Cleaning/Phase+Amp self-cal: Gscale corrections: IF 1: HARTRAO 1.00, KASHIMA 1.00 MOP 0.73, SESHAN25 1.06 VSOP_SC 1.20, USUDA64 0.97. IF 2: No amp self-cal was done since there was no IF 2 data for four simultaneous antennas. Corrections after Gscale were small. Only used global amp+phase selfcal corrections. Final image: 338mJy/beam core, with poor resolution in the NE-SW direction. There were two groupings of clean components around the core, but these were unresolved. #------------------------------------------------------------------------- # Do not delete or alter anything past this line {VSOP Survey Checklist and Worksheet version} : 0.3 #-------------------------------------------------------------------------
