Schematic illustration of the global center of mass relative to the lobes (A) according to Equation (28) and visualization of the actual least squares solution (B). The shorthand symbols are ﹩\theta ={{ \mathcal M }}_{2}/{ \mathcal M }﹩ and ﹩\hat{\theta }={\hat{{ \mathcal M }}}_{2}/\hat{{ \mathcal M }}﹩ (in (A)).
