__Notes on data definition:__

*i(Q)* data are defined according to the standard ISIS histogram data convention: each (x,y) pair represents the top left corner of a histogram. The data can be converted to ordinary data points by replacing each x-value x_{i} by 0.5*(x_{i}+x_{i+1}).

Real-space data (*T(r)* or *D(r)*) are given as conventional (x,y) data points.
