Performance test. The execution time shown as a function of number of grains: dotted line with boxes for (4°/2), and dotted line with diamonds for (6°/2). The purity, i.e. the fraction of correctly assigned G vectors (solid line), shows a linear and decreasing dependency on the number of grains, due to an increasing probability that G vectors from other grains will appear close to the expected location. |
