Fig. 7From: Fusion of wildlife tracking and satellite geomagnetic data for the study of animal migrationError in magnetic intensity (F). A shows the distribution of the error for all three observatories and the black dashed line indicates the mean error = − 21.61, with a 95% CI [− 22.26555, − 20.96664]. The two red dashed lines show the 2.5 and 97.5 percentile of the distribution. B shows the probability density and distribution of error values per station. C shows a scatterplot of the absolute error against the K index and the curve of best fit for each observatory (Lerwick, Hartland, Pedeli)Back to article page
