a: Circular aperture with irregular spikes in a matrix of dimensions 2048 × 2048 pixels. The average diameter = 900 pixels. b: The diffracted image or the intensity impulse response corresponding to the aperture is shown in (a). c: The Normalized PSF plot in the range from 990 up to 1058 pixels obtained from the image is shown in the (b). d: The PSF, for the 1st model in the range from 1040 up to 1100 pixels. The profile is plotted at constant x = 1024 pixels. e: The PSF, for the 1st model in the range from 1040 up to 1100 pixels. The profile is plotted at constant y = 1024 pixels
