Notes. Positions, source sizes and total flux densities are derived in visibility domain.

^(a)

Position offset with respect to and .

^(b)

FWHM source size and position angle.

^(c)

Total flux density. The absolute flux uncertainty is ~ 20%.

^(d)

Total flux density measured by van der Tak et al. (2006) in the visibility domain.

^(e)

Model with a Gaussian plus a point source. See Fig. 2 and text for more discussions.
