One advantage of map interpolation is speed - my code (admittedly not optimized for speed) is about 6x slower than sftools/mapman combination (the advantage of fast fourier transform and explicit use of symmetry). But these days it is only 20ms per atom on a 40,000 reflection dataset (on a modest 2.33GHz Core2 Q8200 CPU). -- "Hurry up before we all come back to our senses!" Julian, King of Lemurs
