Simulation of CME cone and its orthogonal projection in quadrant 3 (near center). From left to right: CME cone with 30° of angular width (Col. 1) and its orthogonal projection (Col. 2) on the solar sphere; the CME cone with 15° of angular width (Col. 3) and its orthogonal projection (Col. 4). From top to bottom: first row shows the radial direction; second and third rows show the case of ±30° from inclination from the X-axis direction in the YZ plane; fourth and fifth rows show ±30° inclination from the Y-axis direction; sixth and seventh rows show ±30° inclination from the Z-axis direction. The orthogonal projections at 0.2R_sun, 0.5R_sun, and 1R_sun are shown by cyan, green, and red markers. The gray markers show the projections of intermediate heights from 0.1–1R_sun.
