Auto-correlation function, ρ, for selected parameters in the model, as estimated from a single chain with 10 000 samples. From top to bottom, the various panels show (1) one pixel value of the CMB component map mCMB; (2) one pixel of the correlated noise map mncorr; (3) the temperature quadrupole moment, a2, 0; (4) the PID-averaged total gain g; and (5)–(8) the PID-averaged noise PSD parameters σ0, fknee, α, and Ap/σ0. In panels with multiple lines, the various colors show Stokes T, Q, and U parameters. In panels with gray bands, the black line shows results averaged over all PIDs, and the band shows the 1σ variation among PIDs. The dashed red line marks a correlation coefficient of 0.1, which is used to define the typical correlation length of each parameter.
