Query: An accurate determination of the Hubble constant from Baryon Acoustic
  Oscillation datasets   Even though the Hubble constant cannot be significantly determined by the
low-redshift Baryon Acoustic Oscillation (BAO) data alone, it can be tightly
constrained once the high-redshift BAO data are combined. Combining BAO data
from 6dFGS, BOSS DR11 clustering of galaxies, WiggleZ and $z=2.34$ from BOSS
DR11 quasar Lyman-$\alpha$ forest lines, we get $H_0=68.17^{+1.55}_{-1.56}$ km
s$^{-1}$ Mpc$^{-1}$. In addition, adopting the the simultaneous measurements of
$H(z)$ and $D_A(z)$ from the two-dimensional two-point correlation function
from BOSS DR9 CMASS sample and two-dimensional matter power spectrum from SDSS
DR7 sample, we obtain $H_0=68.11\pm1.69$ km s$^{-1}$ Mpc$^{-1}$. Finally,
combining all of the BAO datasets, we conclude $H_0=68.11\pm 0.86$ km s$^{-1}$
Mpc$^{-1}$, a 1.3% determination.
