Baryon acoustic oscillation, Hubble parameter, and angular size
  measurement constraints on the Hubble constant, dark energy dynamics, and
  spatial curvature
  In this paper we use all available baryon acoustic oscillation, Hubble
parameter, and quasar angular size data to constrain six dark energy
cosmological models, both spatially flat and non-flat. Depending on the model
and data combination considered, these data mildly favor closed spatial
hypersurfaces (by as much as $1.7\sigma$) and dark energy dynamics (up to a
little over $2\sigma$) over a cosmological constant $\Lambda$. The data also
favor, at $1.8\sigma$ to $3.4\sigma$, depending on the model and data
combination, a lower Hubble constant than what is measured from the local
expansion rate.
