Alternating field demagnetization (AFD) and Isothermal remanence acquisition (IRM – volume normalized) measured on JR-5A spinner magnetometer (noise limit 0.0024 mA/m) at paleomagnetic lab, Pruhonice, Czech Republic. Saturation magnetization is shown in the legend. These 5 samples come from the section with tree rings in the range of 600–1100 years (AD). From top down they correspond to the following years; 1059, 974, 818, 691, and 613.
