Notes.

^(a)

Synthesized beam size in arcseconds and PA in degrees.

^(b)

Aggregated bandwidth used to estimate and subtract the continuum emission in the uv-plane.

^(c)

Flux density integrated over the central 4′′.

^(d)

Fraction of the total continuum flux density found to be extended outside the nuclear concentrations.
