  Using a well-established effective interaction in a rainbow-ladder truncation
model of QCD, we fix the remaining model parameter to the bottomonium
ground-state spectrum in a covariant Bethe-Salpeter equation approach and find
surprisingly good agreement with the available experimental data including the
2^{--} Upsilon(1D) state. Furthermore, we investigate the consequences of such
a fit for charmonium and light-quark ground states.
