Correlation heatmap for \(\alpha\) and \(\beta\) activities for CAM-NWA and CAN-NCV. The numbers in the map are the Pearson’s correlation between observations. For example, in the “correlation matrix for Cell-3”, the number in the cell for DAC-h (alpha)-NWA and DAC-h (beta)-NCV is the correlation between the \(\alpha\) air activity recorded by CAM-NWA and CAM-NCV. A higher correlation denotes a stronger linear relationship. Unscaled observations were used to calculate these correlations.
