The integrations reported in this paper domonstrate conclusively that the elementary coma image is of the size and shape determined by ordinary geometrical optics, and that the only effect of diffraction is to break up the image into an elaborate fine structure of dots and lines of light. Practically all the light in the image is confined within the triangular space between the principal ray at the tip of the figure and the sagittal focus. Between the sagittal and tangential foci there is a small amount of light broken up into a series of approximately concentric curved bands of darkness and light, centred about the brightest part of the image. Even when the amount of coma is very small, comparable to the Rayleigh Limit, the characteristic shape of a typical coma-image is already making its appearance. The accuracy of the theoretical predictions is fully and completely borne out by the actual photographs of a comatic image.
