Notes. The number of splitting frequencies available in each data set is given by n and n1 to n5 are the constituent 72-day time series. The minimum angular degree recovered is given by l in each set. nc and lc represent similar quantities for the common modes between each 360-day and the corresponding 72-day data sets. For details see Sect. 4.1.
