Best-fitting top-hat off-axis jet models with θ_j = 5° (upper panel) and θ_j = 15° (lower panel) for p = 2.1. These models fail to reproduce observations at early times and do not naturally account for the still-rising light-curve, which is a potential signature of structure Γ(θ) in the jet, with an ultra-relativistic core still out of our line of sight. This is explored and quantified in Section 3.3.
