Notes. Square brackets denote hard priors, parentheses indicate Gaussian priors. The “Likelihood” column indicates whether a parameter is used by the CamSpec (C) and/or Plik (P) likelihood. Note that the beam eigenmode amplitudes require a correlation matrix to fully describe their joint prior, and that all but 
are marginalised over internally rather than sampled explicitly.
