Snapshot speeds derived for the selected point features (top panels) and the uniform volume derived by convex hull (bottom panels). The gray shaded plane with the embedded white circle is the ecliptic plane with the Sun (fixed red orb) at the origin of the coordinate system. The viewing angles are 30°N (left column), 30°S (middle column), and with the ecliptic plane face-on (0°; right column). The Sun–Earth line is indicated in all viewing angles. HEE axes are uniform with labels in au. The red solid line in the bottom row corresponds to the propagation axis of the volume’s unweighted centroid, while the dotted red lines show the angular opening of the studied part of the CME with origin in the Sun. Left and middle columns show the part of the CME above and below the ecliptic plane, while the entire volume is shown in the face-on view (right column). The light-gray shaded cuboid in the bottom row shows the overall extent of the studied part of the CME. The color bar corresponds to recovered radial speeds, shaded between 200 and 1000 km s⁻¹. An animation is available in the online version of the journal, showing the result over the entire interval of 9.25 hr. The total playback time is 2 s.
