Data obtained by computation for X-ray imaging of grating without magnification using oriented Gaussian beams

The propagation of X-ray waves through an optical system consisting of grating and X-ray refractive lenses is considered. In this approach, the propagating wave is represented as a superposition of the oriented Gaussian beams. The direction of wave propagation in each Gaussian beam is consistent with the local propagation direction of the X-ray wavefront. The dataset shows the result of computing the intensity of X-rays propagating through a grating and then through a parabolic beryllium lens at a distance of two focal lengths from the lens. The distance between the grating and the optical system in the calculations was taken to obtain magnification factor equal 1 (according to thin lens formula). In total, the data consists of 159201 points. Each point consists of 3 numbers, which are separated by commas. The first and second numbers are responsible for the position (in millimeters) of the point on the plane, the third number - for the intensity values. Points are separated by brackets and enters. The algorithm for computing the dataset is available in the paper: P. Wojda, S.
