We use the 2 per cent distance measurement from our reconstructed baryon acoustic oscillations (BAOs) signature using the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) luminous red galaxies from Padmanabhan et al. and Xu et al. combined with cosmic microwave background data from  Wilkinson Microwave Anisotropy Probe  ( WMAP7 ) to measure parameters for various cosmological models. We find a 1.7 per cent measurement of  H  0  = 69.8 ± 1.2 km s −1  Mpc −1  and a 5.0 per cent measurement ofΩ  m   =  0.280  ±  0.014    for a flat universe with a cosmological constant. These measurements of  H  0  and Ω m  are robust against a range of underlying models for the expansion history. We measure the dark energy equation of state parameter  w  = −0.97 ± 0.17, which is consistent with a cosmological constant. If curvature is allowed to vary, we find that the Universe is consistent with a flat geometry (Ω K  = −0.004 ± 0.005). We also use a combination of the 6 Degree Field Galaxy Survey BAO data, WiggleZ Dark Energy Survey data, Type Ia supernovae data and a local measurement of the Hubble constant to explore cosmological models with more parameters. Finally, we explore the effect of varying the energy density of relativistic particles on the measurement of  H  0 .
