Notes. For polarization, the same parametric functions are employed, but only CMB, synchrotron, and thermal dust emission are included in the model, with spectral parameters fixed to the result of the temperature analysis. The symbol “~” implies that the respective parameter has a prior as given by the right-hand side distribution; Uni denotes a uniform distribution within the indicated limits, and N denotes a (normal) Gaussian distribution with the indicated mean and standard devation.
