Analysis of 3-hourly am data. (a) The grey points form a scatter plot of am against 3-hourly means of power input into the magnetosphere, Pα/Po, generated by averaging over 3 h intervals that are shifted forward in time by the derived best lag of dto = 60 min (see Fig. 7a) relative to the three-hourly intervals in which am is evaluated. The orange points are the mean values averaged in 1% quantile ranges of Pα/Po, i.e., q(0) ≤ <Pα/Po>τ=3h < q(0.01), q(0.01) ≤ <Pα/Po>τ=3h < q(0.02), up to q(0.99) ≤ <Pα/Po>τ=3h < q(1). The black error bars are the plus and minus one standard deviation in those means. The mauve is the best-fit OLS linear regression to the 3-hourly data. (b) the grey points are a scatter plot of the fit residuals Δam for the fit shown in (a): this is the difference between each three-hourly am value and the best fit linear regression value based on the corresponding <Pα/Po>τ=3h value (Δam = am − amfit), plotted as a function of the simultaneous three-hourly mean of the normalized solar wind dynamic pressure <pSW>τ=3h/<pSW>all. The orange points in (b) are means in 1% quantile ranges of <pSW>τ=3h and error bars are plus and minus one standard deviation in the mean Δam. The mauve line is the best linear regression to the 3-hourly values.
