Notes. From left to right the columns indicate component ID, observation day, total flux, component positions in Cartesian coordinates with respect to the kinematic center (C00), full width at half maximum (FWHM) size of the major axis, the corresponding brightness temperature, minor-to-major axis ratio, major axis position angle measured E of N (PA), and relative apparent velocity in the source rest frame. For each, median posterior values are quoted with 95% confidence intervals that were obtained by the MCMC fitting with ∼1.5% systematic amplitude errors added to the data (equivalently 2° phase errors) (see Sect. 2 and Appendix A).
