Fig. S2. Secular variation curves (in blue) obtained from 20 synthetic directional datasets randomly selected from the real British (England and Wales) archaeomagnetic database (Batt et al. 2017). All directions were transferred to the latitude of Paris. (a) Mean α95=3.2°, mean Δt=53 years, (b) Mean α95=3.2°, mean Δt=11 years, (c) Mean α95=1.0°, mean Δt=53 years, (d) Mean α95=1.0°, mean Δt=11 years. Same legends as in Fig. 7.
