Radio triangulation results of FI-type III, FD-type III, FD*-type III, and LF-type II plotted together. The units are solar radii (R_⊙) with the Sun at the centre (0, 0, 0). The dotted lines mark the linear fit to the centroids of the radio sources. Panel a: results in the ecliptic plane. Propagation of all three type III sources is highly non-radial and the two FD-type III bursts seem have a similar propagation path. Panel b: results in the meridional plane. All three bursts show a propagation from high latitude towards the ecliptic plane.
