Notes. Column 2: recovered by VLBI; the errors are estimated according to Fomalont (1999), assuming an additional 10% error for flux density calibration and primary beam correction; Col. 3: size of the fitted circular Gaussian model component at FWHM; Col. 4: minimum resolvable angular size; Col. 5: estimated brightness temperature; Cols. 6–7: astrometric position (right ascension and declination) measured by phase referencing; Col. 8: position error (1σ).
