A comparison between the Bayesian model’s results with conventional reconstruction method and independent GDM models. a Compares different solar activity reconstructions from the Intcal20 ¹⁴C data by the Bayesian model (red line) with the conventional method in which the influences of GDM were removed using the pfm9k.1b (blue dashed line) and the COV-LAKE geomagnetic field model (green dashed line). The light red shading indicates the 2-sigma uncertainty of the Bayesian reconstruction. b Compares GDM recovered from the ¹⁴C data by the Bayesian model (red color) with GDM from the pfm9k.1b models (blue color) and the COV-LAKE models (green color). The lines depict the mean GDM and the color shadings depict the 2-sigma uncertainties of the models
