Pooled coherence estimate across five periods (0.5, 0.6, 0.75, 1.0, 1.5 years) for India (a), Bihar (b), and Uttar Pradesh (c), plotted against estimated basic reproduction number (R 0) and amplitude of the forcing term (Amp or a 0). Pink indicates a better match to periodicity in the mortality data. The location of the maximum coherence is identified with an asterisk (*), and the 95% significance contour (coherence = 0.11) is marked in dark blue
