I(q) function calculator
Enter the shape of the model, its radius or semi-axes R1(x), R2(y), R3(z), range of the scattering vector q from qmin to qmax, number of intervals and scaling-factor for the I(q)-scattering curve. N (odd, 11-501) is the numbers of intervals for the numerical integration. The values are listed in q vs I(q) or log(I(q)), respectively, in arbitrary units and can be copied and pasted from the window into any text-file for further processing and graphical displaying.
