The use of specialized filtering techniques allows the identification of three eigenresonances of the earth near 4800 µHz, which are sensitive to the inner core. Careful programming prevents the formation of interfering intermodulation products and lowers the noise level. The accurately measured frequencies differ by about 1.1% from the PREM predictions.

The time dependent analysis of the normal mode 2S3 near 1244 µHz allows a precise determination of phase and frequency and reveals a phase modulation with a strong geographical dependence. All measurements are performed by a phase-locked loop.
