Line-of-sight velocity distributions for our models. Each row corresponds to a different model, labeled on the left, and each column represents different viewing angle θ. Colored lines are results for different simulation times with legend given in the plot. The distributions are normalized to ensure clarity of the presentation and hence we do not display units on the vertical axes. The distributions are plotted on a linear scale. Some of the features around |u_LOS | ≈ 0 are an artifact of subtraction of CSM that has not collided with the SN ejecta. The black dash-dotted line in the middle panel of model A illustrates the 400 d lower resolution model.
