Notes.

(a)

Calculated from two-dimensional Gaussian fit to the continuum map using the CASA task IMFIT which deconvolves the clean beam from the fitted component size, see Condon (1997) for a discussion of the error estimates in this process. Uncertainties for the peak brightness and integrated flux density include an estimated 3% calibration error added in quadrature to the noise error. The uncertainty for the deconvolved size does not include possible calibration errors.

(b)

Integrated flux density of the core.

(c)

Total integrated flux density of the core and the extended emission. The noise error was calculated by multiplying the image rms noise by the square root of the number of beam areas across the source.

(d)

Core component deconvolved major × minor axis.

(e)

Core component position angle.

(f)

Produced from a combination of the 4.65 and 6.0 GHz observations.
