Figure 8
An example of Bragg peak intensity [I(2\theta)] obtained from an integration of a theoretical image simulated by ray tracing. The expected result is a Gaussian peak having an FWHM of 3 pixels. The integration is performed with or without subpixel interpolation, for an azimuthal integration over 2° around the azimuth angle of 90°. When no subpixel interpolation was used, different values for the increment [\delta 2\theta] were investigated as a function of the pixel aperture ([\delta 2\theta = {{2} / {3}}] pixels and [\delta 2\theta = {{4} / {3}}] pixels).
