Probability density functions (pdf, 1D and 2D) of r^TE and only for bin 2 and bin 3 together with 1, 2, and 3σ contour levels for the observed data (left panel), the simulations without Planck noise (central panel), and the simulations with Planck noise added (right panel). The blue lines indicate the observed values in P16XXX and P18XI of and r^TE = 0.36. On top of the 1D pdf the mean values and standard deviations (also represented by black vertical dashed lines) are shown. These plots were made with the PYTHON CORNER package (Foreman-Mackey 2016).
