  1. The six modes are the fundamental quasi-radial (\({{{{{\mathcal{l}}}}}}\) = 0) mode F and its first overtone H1, the fundamental quadrupole (\({{{{{\mathcal{l}}}}}}\) = 2) mode 2f and its first overtone 2p1, as well as the fundamental hexadecapole (\({{{{{\mathcal{l}}}}}}\) = 4) mode 4f and its first overtone 4p1, all predominantly excited under the perturbation with the corresponding l index. All eigenfrequencies are in kHz and rounded off to two decimal places. The undetermined eigenfrequencies in specific models are denoted by ‘N/A’. The missing eigenfrequencies in the column of F mode are due to unsatisfactory data quality in Gmunu simulations of T1K8 and T1K11 models under \({{{{{\mathcal{l}}}}}}\) = 0 perturbation, while the missing eigenfrequencies in the columns of 4f and 4p1 modes are due to the hexadecapole (\({{{{{\mathcal{l}}}}}}\) = 4) modes being masked by the quadrupole (\({{{{{\mathcal{l}}}}}}\) = 2) modes in Gmunu simulations of the most magnetized models under \({{{{{\mathcal{l}}}}}}\) = 4 perturbation.
