The difference between the `centroid' and `most probable' structure factors. (a) Cut the centre out of a paper plate. (b) Balance the disc on a pen. The centre of mass is at the centre. (c) Now clip two unequal weights to the edge of the plate. (d) The balancing point is between the two weights (analogous to the `centroid' structure factor) and not on the heaviest weight (analogous to the `most probable' structure factor).
