On the resolution of regional archaeomagnetism: Untangling directional geomagnetic oscillations and data uncertainties using the French archaeomagnetic database for between 1000 and 1500 AD as a guide

Fig. S1. Description of the 303 directional results dated between 1000 and 1500 AD obtained from England and Wales (Batt et al. 2017). a) Histogram of experimental uncertainties (σ₉₅). Pale green, all data; dark green, only data with Δt ≤ 150 years. b) Histogram of age uncertainties (Δt) for all available data. Pale green, data with Δt > 150 years; dark green, data with Δt ≤ 150 years. c) Temporal distribution of age intervals of the available data with Δt ≤ ⃞⃞⃞ years.
