Notes. The columns indicate the symbol for each parameter, the prior used for exploration (square brackets denote uniform priors, parentheses indicate Gaussian priors), and definitions. Beam eigenmode amplitudes require a correlation matrix to fully describe their joint prior and so do not appear in the table; they are internally marginalized over rather than explicitly sampled. This table only lists the instrumental parameters that are explored in the released version, but we do consider more parameters to assess the effects of beam uncertainties and beam leakage; see Sect. 3.4.3.
