Extended Data Fig. 5: Direct comparison of reconstructed solar modulation parameter with sunspots.
From: Eleven-year solar cycles over the last millennium revealed by radiocarbon in tree rings
Sunspots32 (black) with the solar modulation parameter calculated from ETH (blue) and QL (orange) data. The blue band indicates the estimated 2 sigma errors of the reconstructed solar modulation parameter of the ETH data by using 1000 Monte Carlo simulations.
