Core position as a function of wavelength for scattered jet models. Left panel: Squares indicate the core position relative to the central BH at 13.6 mm, 7 mm, and 3.5 mm (22/43/86 GHz) for unscattered jet models. Triangles indicate the core position for jet models that have been scattered with the kernel. Colors represent different inclination angles (i) with respect to the observer’s line of sight. For all models, the orientation on the sky of the spin axis is PA = 0°. Solid lines (jet models) and dashed lines (jets scattered with the kernel) show the best-fit power law using a least-squares fitting method. Error bars indicate 1σ uncertainty in the core position data points. Errors in the fit parameters and χ² are summarized in Table C.1 of the support material. The values for the inclination (i) and the power-law index (p) are given in the legend. Right panel: Same as the left but showing jet models (squares) scattered with the kernel and also including refractive scattering (diamonds).
