Notes. The phase centers for APM 08279+5255 and NCv1.143 are the pointing positions (Table 1). The ∼ 9″ shift in δRA of APM 08279+5255 was due to a shifted observational phase center. The δRA and δDec positions are the center of the Gaussian profiles relative to the phase center. The rest of the fitted parameters – the major and minor axis of the ellipse, rmajor and rminor and the position angle PA are all consistent across different spectral windows within the uncertainties. As they are irrelevant to the purpose of this work, we do not list them here.
