Tomographic reconstruction of the full heliosphere from varying observer configurations. We compare ecliptic (top) and latitudinal slices at 135° longitude (bottom) for the ground truth and reconstructions using all available viewpoints, only ecliptic viewpoints, three ecliptic-plane observers, and a high-latitude configuration (polar). Observer positions are indicated by blue arrows. The results show that additional viewpoints improve reconstruction quality, particularly for the background solar wind. Reconstructions are more accurate when the target structures are viewed from multiple angles (latitudinal slices), while reconstructions within the observer plane are less reliable.
