Maps of Log₁₀ of column density (range between 10^-15 g/cm² and 10^-12 g/cm²) seen from three different points of view; superimposed are the points of the clouds that belong to the CME. Points obtained from the polarization ratio technique are red, points of the folded centre of mass are green, and points of the centre of mass are light blue. a) Point of view parallel to direction z and (x,y) coordinates of clouds of points; b) point of view parallel to direction y and (x,z) coordinates of clouds of points; c) point of view parallel to direction x and (z,y) coordinates of clouds of points. A movie of these panels is available online.
