Modeled images of blazar TXS 2013+370 at 15 GHz. The 2 dimensional circular Gaussian components model the flux density distribution along the jet. The data were imaged under a uniform weighting scheme and without uv-tapering (all the visibilities weighed equally, independent of their uv-distance). The contour levels are set to 0.25,0.5, 1, 2, 4, 8, 16, 32, and 64% Jy beam⁻¹ of each image peak flux density (see Table B.1). All the images are convolved with a common beam of 0.8 × 0.5 mas at PA −16°. The time corresponding to each image is indicated in the x-axis.
