From: A reappraisal of instrumental magnetic measurements made in Western Europe before AD 1750: confronting historical geomagnetism and archeomagnetism

Fig. 3

Same legend as in Figs. 1 and 2, but with only the Thellier (1981) and gufm1 directional curves. The black-red curve shows the average historical geomagnetic field variation curve computed in the present study for Western Europe, after removal of seven individual D, I values (dashed white circles).
