This value matches the values from UMRAO (tho the time range does not overlap). Also I reckon the he did not correct for Penticton scale errors. The Hobart/Mop baseline is high, the short baseline structure is complex. I have put in a narrow (non-physical) elliptical gaussian The pre-launch fits pretty well, but underestimates the VSOP baselines. The jet axis is correct. J0811+01 flux is 0.5Jy, which is reasonable from UMRAO data. #--------------------------------------------------------------------------- # Do not delete or alter anything past this line {VSOP Survey Checklist and Worksheet version} : 0.3 #---------------------------------------------------------------------------
