We describe the Bayesian Analysis of Nuclear Dynamics (BAND) framework, a cyberinfrastructure that we are developing which will unify the treatment of nuclear models, experimental data, and associated uncertainties.

The strongest gains would likely come from new data on the spin observables $\Sigma_{2x}$ and $\Sigma_{2x^\prime}$ at $\omega\simeq140$ to $200$ MeV and $40^\circ$ to $120^\circ$.
