Hi Dirk,
If you have a N points of a 1D real discrete function, there will be Fourier coefficients indexed h=0,1,2,...,N-1. Taking N as odd, there will be int(N/2)+1 independent Fourier coefficients but your h(max) will in fact be 'N-1'. In crystallography we write h(N-1) as h(-1) etc and tend to ignore these Freidel mates. If cell length is then 'a' the sampling distance is a/N which is related to h(max) but you need to be careful how to defined h(max) Adam
