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 H0 = 69.8 ± 1.2 km s−1 Mpc−1 and a 5.0 per cent measurement of for a flat… Expand
