Distributions and relative weight of types of Si IV line profiles as a function of Si IV line intensity and ﹩\cos (i)﹩. The first two histograms show distributions (each normalized to its peak) of Gaussians and κ-like profiles as a function of Si IV intensity and ﹩\cos (i)﹩. The third plot shows the fraction of Gaussians and κ-like profiles in each ﹩\cos (i)﹩ bin. The last plot shows a 2D histogram of the ratio of κ-like versus Gaussians as a function of Si IV intensity and ﹩\cos (i)﹩. All plots are for the field of view shown in Figure 2.
