Notes. In the case of BTr, the unresolved central (m = 0) component f0 is determined from the midpoint of the observed f± 1 components and P0 is the corresponding period. The split frequency δfrot is then half the difference between the m = 1 and m = −1 component and ng gives the radial order of the best-fit model frequency (see Sect. 7). In the case of SMEI (labeled by an arrow in the first column), f0 and δfrot are determined from a Lorentzian fit to the data. Frequencies and periods are given in units of  d-1 and d, respectively.
