Cylindrical profile of π^{﹩\arcmin﹩} vs. ﹩\vert z^{\prime }\vert ﹩ for the CS echoes inclined by ﹩i_{x}=45^{\circ }﹩ and ﹩i_{y}=8^{\circ }﹩. Symbols correspond to points in Figs. 15g–15i, with closed and open circles denoting cyan and yellow extended flux points, and crosses marking the red hourglass. Points below the solid line are potential members of the CS hourglass, and comprise distribution "A," while those also under the dashed line are distribution "B" (§ 8.1.1).
