Selected 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. The images show two newly ejected jet components appearing in August 2015 (J4) and June 2018 (J5) that can be tracked back until April 2015 and February 2017, respectively. In this work we focus on these two newly ejected components. Additional plots of the epochs observed before April 2015 are shown in Appendix B in Figs. B.1–B.2.
