a The autocorrelation of the aperture shown in the Fig. 1a, where the total band width = 1280 pixels which is two times the aperture width 640 pixels. b The autocorrelation of the aperture shown in the Fig. 1b, where the total band width = 1280 pixels which is two times the aperture width 640 pixels. c The autocorrelation of the aperture shown in the Fig. 1c, where the total band width = 1280 pixels which is two times the aperture width 640 pixels. d The autocorrelation of the aperture shown in the Fig. 1d, where the total band width = 1280 pixels which is two times the aperture width 640 pixels
