Scatterplot of all examined marks (except the needle puncture controls) arranged in two dimensions by area A and intensity ratio I 1 / I 2 . A multiple-threshold criterion, for example I1/I2 < 1.2 and A < 0.6, improves the separation of false-positive marks from true-positive marks: 87% of the true-positive marks lie inside the rectangle, whereas only 8% of the false-positives fall into the same rectangular region.
