Abstract

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.
