XX. 74 The impression they convey would much more nearly accord with what actually occurs if the curves showed not the intensity of light in the various directions, but the lines along which the lighting is equal at any point. Such curves may be called ‘isophotals’, and while they are of the same general shape as intensity curves, their dimensions are as the square root of the radii.Ibid., The tendency of enclosing an arc.., either in the interior gas globe or more particularly in the outer diffusing globe, is to make such an isophotal curve approach more nearly a circle.1930Astrophysical Jrnl.
