Try to use as many different tracks as possible; 0010 * avoid using the same track all the time. 0011 * b. Use the most energetic tracks. 0012 * c. Try not to group the most energetic tracks together. 0013 * Try to group more energetic tracks with less energetic tracks. 0014 * We assume collimated bundles here, so this is why. 0015 * d. Perform optimally. Do not sort more tracks (by total energy, see b) 0016 * than necessary. 0017 * e.
