Uniformly weighted 43 GHz VLBA total intensity images of the FSRQ 4C +01.28 with the fitted Gaussian components overlaid. S_tot is the total integrated flux density, S_peak is the highest flux density per beam, and σ is the noise level. The gray ellipse in the bottom left corner corresponds to the beam. The contours begin at 3σ and increase logarithmically by a factor of 2. The image parameters are listed in Table C.1.
