Fig. 4


spectra likelihood posteriors on the r and Ad parameters derived from the simulations of the BICEP2-Keck and Planck 353 GHz data, using: 150 and 353 GHz channels (BKP, red); and 95, 150 and 353 GHz channels (BK(+95), blue). The 1D posteriors of r (marginalized over and Ad) and of Ad (marginalized over and r) are shown in the left and middle panels (blue and red lines, respectively). The input value in our simulations for the dust amplitude at 353 GHz (4.5 μK2 at = 80) is indicated as a dashed line. The 2D posterior marginalized over is presented in the right panel (68% in darker shading and 95% in lighter shading).
