Predicted 5 GHz curves for the tidal disruption candidate D3-13 (Gezari et al. 2009) for the internal jet model in the optimistic scenario (Eq. (3a)). The existing upper limits on the 1.4 GHz flux density (Bower 2011) are shown with blue triangles, pointing left and right to indicate the uncertainty on the time of disruption. The downward pointing triangles labeled “2012” show our upper limits to the 5 GHz flux. For cosi < β_j, the peak of the light curve decreases in time and magnitude as i increases, because a fixed observed frequency corresponds to a smaller radius where the jet becomes optically thin to synchrotron self-absorption (i.e., z_ssa ∝ δ/ν). For cosi > β_j the light curve is compressed due to time retardation.
