Parameter correlations for Plik TT+lowTEB (top), Plik TE+lowTEB (bottom left), and Plik EE+lowTEB (bottom right). The degeneracies between foreground and calibration parameters do not strongly affect the determination of the cosmological parameters. In these figures the lower triangle gives the numerical values of the correlations in percent (with values below 10% printed at the smallest size), while the upper triangle represents the same values using a colour scale.
