Notes.

^(a)

ID of kinematic component.

^(b)

Flux density of the component.

^(c)

Distance of the component to center of the map.

^(d)

Position angle of the component relative to the center of the map.

^(e)

Major axis of the Gaussian component.

^(f)

Logarithmic value of the brightness Temperature.

^(g)

As noted in Sect. 2.1, the flux density values obtained for the third VLBI measuremnt might be systematically underestimated by 22%.
