Each column is the unweighted arithmetic mean of that column across the nine readings in the window. Nine readings per window was chosen before the figures were computed, as roughly a third of the series on each side; the middle is excluded so the two windows do not overlap. Means of ratios are means of the daily ratios, not ratios of the means.","unit":"mixed","license":"Afrobeats Wire's compilation and analysis are licensed CC BY 4.0.
