Table 1

3D space considered for the mode identification and parameter estimation.

0 (s) frot (day−1) αg
Min value 2000 0.000 0.000
Max value 6000 3.000 1.000
Small step 20 0.002 0.125
Large step 20 0.010 0.125

Notes. The large step was used to generate a coarse parameter space for the mode identification, while the small step was subsequently used to generate a dense parameter space to refine the estimation of frot and ∏0.
