Comparison between the St Andrew’s cross angles predicted by the dispersion relation and measured in Fig. 4.
|Filtered frequency||N1 (mHz)||αth (deg)||αm (deg)|
|0.02 mHz||0.15 ± 0.02||82.34 ± 1.03||85.4 ± 2.29|
|0.03 mHz||0.17 ± 0.02||79.84 ± 1.21||84.29 ± 3.59|
|0.04 mHz||0.18 ± 0.02||77.16 ± 1.45||82.2 ± 1.79|
Notes.Owing to the zooming effect, the α angles actually look smaller in the lower panels of Fig. 4.
