Abstract
We obtain the reduced CMB data from WMAP9, WMAP9+BICEP2, Planck+WP and Planck+WP+BICEP2 for the CDM and CDM 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 BICEP2 results in a higher value of the Hubble constant especially when the equation of state of dark energy and curvature are allowed to vary. For the CDM model with curvature, the estimate of the Hubble constant with Planck+WP+Lensing is inconsistent with the one derived from Planck+WP+BICEP at about 1.3 confidence level.
