Table 1.

Global characteristics of the three normal modes as displayed in Fig. 2.

Mode ν0( μHz) Δν0( μHz) Γ( μHz) ΔΓ+( μHz) ΔΓ( μHz)
1 2397.95 0.42
2 3540.41 0.98 50.00 2.17 2.08
3 4955.14 4.39 319.28 14.08 13.48

Notes. ν0 is the central frequency, Δν0 is the error on the frequency, Γ is the mode linewidth, and ΔΓ+, ΔΓ are the upper and lower errors on the mode linewidth, respectively. We note that the first mode (mode 1) is not resolved so that the only constraint we get is that its linewidth is lower than the frequency resolution, i.e. Γ ≤ 25 μHz.
