Real data results: power spectra of the interferometric signals of different pairs. Between sources 14 and 8 of the AAL, only an iso-frequency coupling (peak at 0 Hz) is present (a), sources 57 and 40, only a cross-frequency coupling (peak at -14 Hz) is present (b), sources 22 and 7, both iso and cross-frequency coupling (peaks at 0 and 8 Hz) are present (c), sources 23 and 13, in addition to the iso-frequency peak, several cross-frequency couplings (peaks at -8, 0 and 18 Hz) are present (d)
