Notes.

(a)

Source identification numbers in agreement with those listed in the first column of Table 1.

(b)(c)

,Major and minor FWHM of the 2D best-fit Gaussian of the flux maps deconvolved from the beam. Point-like sources are explicitly indicated. In these cases, minor FWHM of the synthesised beam is taken as upper limit on the angular dimension of the emitting region. Uncertainties on quantities are statistical errors ignoring any possible systematic biases.
