VLBA images of H1426+428 at 8.4 GHz. The top row shows the images obtained with natural weighting, while the bottom row shows the images obtained with uniform weighting. The axes are labeled in milliarcseconds (mas). Numerical parameters of the images are given in Table 2. The location of the center of the circular Gaussian (excluding the Gaussian representing the core) that was fit to the visibilities is marked with an asterisk. Parameters of the Gaussian models are given in Table 3.
