Parameters of the fiducial flat ΛCDM cosmological model used for this analysis, the flat ΛCDM model derived from Planck and low-ℓ WMAP polarization data, “Planck + WP” (Planck Collaboration XVI 2014), and a flat ΛCDM model derived from the WMAP, ACT, and SPT data (Calabrese et al. 2013).

Notes. The models are defined by the cold dark matter, baryon, and massive neutrinos densities, the Hubble constant, and the number of light neutrino species. The sound horizon at the drag epoch, rd is calculated using CAMB (which can be approximated with Eq. (55) of Anderson et al. (2014) to a precision of 0.1%).
