Average Procrustes distance from the centroid to each replicate for every Type I, II or III landmark in the analysis.

Data for individual Procrustes alignment indicate that only the 40 replicates for each individual were used in the calculation; full Procrustes alignment includes all replicates for all individuals in a single Procrustes alignment. Bolded values indicate the six largest average Procrustes distances for the alignment using all users; these were the landmarks removed in the Reduced Landmark dataset.
