Waveform specification coverage

This page maps the public Torch and JAX dispatch names to a model or variant. It also lists standalone waveform classes omitted from those dispatch registries. Versioned slice means that a canonical specification and independent scalar reference cover only the stated slice in the waveform library. Provisional means the waveform is implemented but does not yet have that complete, source-linked specification/reference contract. "Separate SEOBNR track" identifies the retained external-data ROM wrapper without claiming that this library work validates its external calibration asset.

The retired prototype record preserves the former SEOBNR, TEOBResumS, and native-ROM routes outside this current-public surface. The model names below link to the most relevant existing guide or evidence record; those links are not substitutes for a six-section canonical specification. The support catalog, model evidence manifest, and validation overview remain the places to assess specific options and numerical evidence. A dispatch alias is not a separate mathematical model. Aliases without a backend label occur in both dispatchers; exceptions are labeled in the table. The same alias can still select different backend class routes, as the Pv2 ledger explains. Direct class only means use the class API, not the FD/TD dispatcher.

The XPHM SpinTaylor and PNR rows are option-selecting dispatch variants of IMRPhenomXPHM. IMRPhenomPv2 is a distinct JAX class; Torch selects a Pv2 path through its IMRPhenomP dispatch class. The T family is native time domain. Other FD models may be converted to time series by get_td_waveform; that conversion does not make them native TD approximants. The official v4 ROM uses external data; direct SEOBNR_ROM class construction selects this same evaluator. The former seobnrv5rom alias selected a different native surrogate and has been retired; it must not silently select the official ROM. Sine-Gaussian glitch wavelets and HybridMECO are supporting tools rather than standalone dispatched waveforms. SpinPrecessionODE is retired.
