Slopes m′(top) and intercepts c′(bottom) of the linear fits to the distribution of log (p) and in the simulated observations, as a function of viewing angle α. The lag is δ = 16′. The dashed blue lines indicate the values for the large-scale fit presented in Sect. 2.5, the dashed red lines represent the average slope and intercept over the range of α, and the grey areas indicate ± 1σ around the mean, with the standard deviation σ computed statistically over all angles.
