a Circular aperture of linear distribution with 8 spikes in a matrix of dimensions 2048 × 2048 pixels. The average diameter = 1024 pixels. b: The PSF image or intensity impulse response is corresponding to the aperture shown in (a). c: The Normalized PSF plot in the range from 990 up to 1058 pixels is corresponding to the image shown in (a). It is shown that the central peak is found at 36 pixels. d: The Normalized PSF plot in the range from 1014 up to 1034 pixels at y = 1024 pixels is corresponding to the image shown in (a). e: The Normalized PSF plot in the range from 1014 up to 1034 pixels at x = 1024 pixels is corresponding to the image shown in (a)
