Notes. S_s, S_m, and S_l are the correlated flux density on the shortest (60−70 × 10⁶λ), intermediate (100−200 × 10⁶λ), and longest (1100−1500 × 10⁶λ) baselines, respectively; S_f and θ_d are the flux density and the size of the fitted Gaussian model; T_b is the brightness temperature in the parent-galaxy rest-frame.

^(a)

It is fitted with a double point-source model, the separation of the two points is 0.16 mas, the flux density ratio is 3:1.
