Notes. The values were obtained from the 15 consecutive radial orders between 1800 μHz ≤ ν< 3790 μHz, and for 5 consecutive radial orders in the low-frequency range 1800 μHz ≤ ν< 2450 μHz, 5 consecutive radial orders in the mid-frequency range 2450 μHz ≤ ν< 3110 μHz, and 5 consecutive radial orders in the high-frequency range 3110 μHz ≤ ν< 3790 μHz.
