Notes. Critical distances (see Sect. 3 for details) for various cases: four directions for the location of the artificial sources – along the major axis of the beam, along the minor axis, along the jet direction claimed by Li et al. (2013), and along the direction claimed by Yusef-Zadeh et al. (2012); two total flux densities of the artificial sources – 0.2 Jy and 0.55 Jy; and two simple geometries – a single-point source and a knotty jet composed of ten equidistant point-like components. Values outside [inside] brackets are in units of milliarcseconds (Schwarzschild radii). All values are projected distances.
