**I(q) calculator of a lattice**
This Javascript calculates the scattering curve of a 1D (lamellar),
2D (hexagonal), or several 3D (cubic) lattices, respectively.
Enter the lattice type, the lattice spacing (size), the number n of peaks
(1 to 8, peak c(0) at q=0 is not counted), their peak areas c(i), the
FWHM and an optional constant y-offset of the peaks. For Nr points I(q) from q = 0 to ~ n*2*Pi/size with a
scaling factor f will be calculated.
The values are listed/plotted in I(q) vs q in arbitrary units and can be copied
and pasted from the window into any text-file for further processing
and graphical displaying. Permitted Bragg-reflections for selected lattice types are listed
