Planck data reconsidered

The authors perform an independent analysis of the Planck data and discuss the tension between the parameters (Hubble constant etc.) derived by the Planck team and those obtained from a number of other astronomical measurements. They find that a particular data set (217 GHz maps) drives this tension, which they are able to decrease, confirming the standard six parameter $\mathrm{\ensuremath{\Lambda}}\phantom{\rule{0}{0ex}}C\phantom{\rule{0}{0ex}}D\phantom{\rule{0}{0ex}}M$ model.
