IMRPhenomXPHM is a new computationally efficient phenomenological model for precessing binary black hole gravitational-wave signals that incorporates higher-order modes via twisting-up maps from non-precessing waveforms.
The multibanding algorithm is parameterized by a threshold, which describes the permitted local interpolation error for the phase in radians
