Table 1
Parameters of the base ΛCDM cosmology (as defined in PCP13) determined from the publicly released nominal-mission CamSpec DetSet likelihood [2013N(DS)] and the 2013 full-mission CamSpec DetSet and cross-yearly (Y1 × Y2) likelihoods with the extended sky coverage [2013F(DS) and 2013F(CY)].

Notes. These three likelihoods are combined with the WMAP polarization likelihood to constrain τ. The column labelled 2015F(CHM) lists parameters for a CamSpec cross-half-mission likelihood constructed from the 2015 maps using similar sky coverage to the 2013F(CY) likelihood (but greater sky coverage at 217 GHz and different point source masks, as discussed in the text). The column labelled 2015F(CHM) (Plik) lists parameters for the Plik cross-half-mission likelihood that uses identical sky coverage to the CamSpec likelihood. The 2015 temperature likelihoods are combined with the Planck lowP likelihood to constrain τ. The last two columns list the deviations of the Plik parameters from those of the nominal-mission and the CamSpec 2015(CHM) likelihoods. To help refer to specific columns, we have numbered the first six explicitly. The high-ℓ likelihoods used here include only TT spectra. H0 is given in the usual units of km s-1 Mpc-1.
