Recovered posterior distributions for a selected set of parameters from two PIDs and detectors. The contours indicate 68 and 95% confidence regions, while the dashed lines (in the respective color of the contours) show the true input value of each of the PIDs. The contours below (blue) and above (orange) the diagonal correspond to PIDs 3003 and 5515, respectively. From left to right along the horizontal axis, columns show (1)–(3) one arbitrary CMB map pixel in Stokes I, Q, and U; (4)–(6) correlated noise for the same pixel and Stokes parameters; (7) the CMB intensity quadrupole amplitude a_2, 0; (8) gain g; and (9)–(12) the four correlated noise parameters, ξⁿ = {σ₀, f_knee, α, A_p}. Note: the 1D histograms of the first seven parameters are completely overlapping since these parameters are independent of PID.
