The Impact of Finite-Differencing Errors on Binary Black Hole Merger Templates
AIP Conference Proceedings
We study the impact that inaccuracy of numerical templates can have on the detection of gravitational waveforms via matched filtering. As a first step toward the analysis of templates from binary black hole mergers we use numerical ringdown templates generated by a Zerilli code for several resolutions. In case of this toy model, we find that the inaccuracies only affect the detection at higher thresholds, causing a reduction and a drift in the signal parameter space spanned by the template.
