Averaged \(R_{I-By}\) spectra for 6 groups of pulsations: 1)-2) small-scale \(S_{\gamma }\) and large-scale \(L_{\gamma }\) in accordance to the N–S spectral coherence; 3)-4) \(L_{\gamma }S_{\varphi }\) and \(L_{\gamma }L_{\varphi }\) are the small-/large-scale sub-groups of the \(L_{\gamma }\) group defined in accordance to the phase difference; 5)-6) \(L_{\gamma }L_{\varphi }S_P\) and \(L_{\gamma }L_{\varphi }L_P\) are the small- /large-scale sub-groups of the \(L_{\gamma }L_{\varphi }\) groups defined in accordance to the South-to-North PSD ratio
