A display of three-body final states in two independent pairwise squared <invariant masses>. For a parent of <mass> $M$ decaying into daughters of <masses> $m_1,m_2,m_3$, <four-momentum conservation> gives $s_{12}+s_{13}+s_{23}=M^2+m_1^2+m_2^2+m_3^2$. A narrow intermediate two-body resonance fixes one pairwise <invariant mass> and appears as a band.
