I have converted non-uniform step data by rebinning. I use a spline
function to fit the data locally, then interpolate at the desired values of
2theta. Getting the standard deviations of the counts can be a problem, but
the rest is not too complicated. Numerical Recipes lists suitable spline
routines.
