Quality factor Q of stereoscopic triangulation as a function of the spacecraft separation angle αsep, which is a function of the accuracy A of triangulated stereoscopic positions and the stereoscopic correspondence quality factor C. The best quality (within a factor of 2) occurs in the range of αsep = 22°–125° with an optimal separation angle of 68°. Figure reused from Aschwanden et al. (2012) with the authorisation from Springer.
