Pearson correlation coefficient. Each cell color represents the Pearson correlation coefficient between populations at different time windows \(t_{1}\) and \(t_{2}\), given by Eq. (2). Both time windows are given in 24-hour notation. The values that colors represent are illustrated in the color bar: darker colors indicate higher correlations between two populations. The hourly populations in night time are highly correlated with each other, while those in the daytime are also highly correlated with each other
