摘要We obtain the reduced CMB data {l(A), R, z(*)} from WMAP9, WMAP9+BKP, Planck+WP and Planck+WP+BKP for the Lambda CDM and wCDM models with or without spatial curvature. We then use these reduced CMB data in combination with low-redshift observations to put constraints on cosmological parameters. We find that including BKP results in a higher value of the Hubble constant especially when the equation of state (EOS) of dark energy and curvature are allowed to vary. For the Lambda CDM model with curvature, the estimate of the Hubble constant with Planck+WP+Lensing is inconsistent with the one derived from Planck+WP+BKP at about 1.2 sigma confidence level (CL).
