Radio light curves at ν = 4.86 GHz for a fallback-powered jet viewed from observer angles θ_obs = 0, 0.2, 0.4, 0.8, and π/2. The jet follows the fallback luminosity history shown in Figure 1, has an initial half-opening angle θ_jet = 0.1, and an isotropic-equivalent energy E_iso = 4 × 10⁵³ erg. As the viewing angle increases, the observed flux decreases and the radio peak shifts to later times as relativistic beaming becomes progressively weaker. The suppression of the radio emission for off-axis observers is substantially stronger than predicted by impulsive models because the limited lateral expansion demonstrated in Figure 8 prevents a substantial fraction of the jet energy from being redistributed toward larger angles.
