Abstract 1. HH and VSOP available for 3 hrs. MP only for 1.5 hrs. \\ 2. Strong fringes even for space baselines. Use 2min solution for FRING and 1min solution for phase in CALIB. \\ 3. Total flux = 3.4 Jy and almost unresolved with VLBA. \\ 4. Obtained gain factor for all three telescopes using consistency with ground at 150 Mlambda and continuity between ground and space baselines. Done empirically. This was the only gain calibration applied. \\ HH factor 35; MP factor 26; VSOP factor 120 used \\ HH factor 23; MP factor 31; VSOP factor 125 expected (see Scott reduction) \\ Results in agreement with Bill Scott, but flux densities have increased. \\ 5. One component fit to data with reasonable diameter. \\ 6. This survey source need not be done again, even with just 1.5 ground telescopes.
