Erratum: Extracting linear and nonlinear quasinormal modes from black hole merger simulations [Phys. Rev. D <b>109</b>, 044069 (2024)]

Abstract

In this paper, when we constructed the hyperfit models in Sec.IV, we assumed that the leading dependence of the amplitude for the odd-m modes is proportional to as 0, where ffiffiffiffiffiffiffiffiffiffiffiffi ffi 1 -4 p .We thus divided the amplitudes by for those modes and fitted the result with a multivariate polynomial with the procedure explained in that section.However, while the dependence is exact for binary black hole (BBH) mergers where the progenitors have equal spins, it is only an approximation for BBHs with unequal spins (i.e., with - 0).Therefore, we no longer divide by for modes with odd m, meaning that Eq. ( 10) should now read
