Notes. Similar description as for Table A.1, following what presented in Sect. 5.4. The ℓ = 3 cases refer to those peaks flagged as candidate octupole modes according to Sect. 5.5, i.e., located inside the octupole mode search range, hence are not intended as yet confirmed ℓ = 3 mode of the analysis.
