... data processing steps. As a prototype for other steps, we analyze how the center, shape, and size of input Gaussian beams are mapped by the Radon transform. We recognize Gaussian beams, points, and lines as special cases of parabolas where curvature is allowed to be complex-valued. This yields an...
