" \n", " Figure 3a: Comparison between two different sampling strategies to determine a mean paleomagnetic pole position in the presence of outliers for a fixed number of total samples (n = 100). The red histograms and curve are strategy 1 where we have one sample per site (n0 = 1), one hundred sites (N = 100) and we use the Vandamme filter. The blue histograms and curve are strategy 2 where n0 = 5, (N = 20) and we filter all the outliers (perfect detection algorithm) for (a) p_outlier = 0.10.\n", " | \n", "
