More on Tanaka-Tagoshi Parametrization of post-1PN Spin-Free Gravitational Wave Chirps: Equispaced and Cardinal Interpolated Lattices

TL;DR

This paper extends previous work on the Tanaka-Tagoshi parametrization of gravitational wave chirps, demonstrating its validity with the full 2.5PN phase expansion, and explores lattice interpolation methods.

Contribution

It shows that the Tanaka-Tagoshi parametrization remains valid when incorporating the full 2.5PN phase expansion, and discusses equispaced and cardinal interpolated lattice approaches.

Findings

Validation of the parametrization with 2.5PN phase

Effective lattice interpolation methods identified

Enhanced accuracy in gravitational wave chirp modeling

Abstract

The conclusions obtained in gr-qc/0101067 are shown to be valid also if the full 2.5PN expansion of the chirp phase is used.
