Measuring the Hubble constant and spatial curvature from supernova
  apparent magnitude, baryon acoustic oscillation, and Hubble parameter data
  Cosmic microwave background (CMB) anisotropy (spatial inhomogeneity) data
provide the tightest constraints on the Hubble constant, matter density,
spatial curvature, and dark energy dynamics. Other data, sensitive to the
evolution of only the spatially homogeneous part of the cosmological model,
such as Type Ia supernova apparent magnitude, baryon acoustic oscillation
distance, and Hubble parameter measurements, can be used in conjunction with
the CMB data to more tightly constrain parameters. Recent joint analyses of CMB
and such non-CMB data indicate that slightly closed spatial hypersurfaces are
favored in nonflat untilted inflation models and that dark energy dynamics
cannot be ruled out, and favor a smaller Hubble constant. We show that the
constraints that follow from these non-CMB data alone are consistent with those
that follow from the CMB data alone and so also consistent with, but weaker
than, those that follow from the joint analyses of the CMB and non-CMB data.
