Dear James, important and educational points! This triggers some thoughts ... The one point where I don't quite agree is with "What about filtering out the noise? An ideal noise suppression filter has the same shape as the signal (I found that in Numerical Recipes), and the shape of the

Series termination is a problem when you leave out Fourier coefficients that have significant amplitude. Back in the old days when we cut data aggressively it was something to worry about. Now that most everyone integrates down to very weak intensities it shouldn't be much of a problem.

Hello Matthias, Excellent point. Most of the the ordered water are easily visible at 2 rmsd. The central disordered (or partially occupied) water becomes visible only at 1.3 - 1.4 rmsd, and it is very visible at 1 rmsd (which I have displayed all of the maps). In your opinion, do you think this
