On the accuracy of gravitational-wave observations — •Frank Ohme — Max-Planck-Institut für Gravitationsphysik (AEI), Hannover, Deutschland — Leibniz-Universität Hannover, Deutschland

The catalogue of gravitational-wave observations continues to grow with every LIGO-Virgo observing run. Nearly 100 signals from compact binary mergers have been identified in the first three runs. Each signal's source properties are determined by comparing theoretical models with the data. This process is subject to two categories of uncertainties (or errors): statistical errors account for the presence of detector noise; systematic errors arise from inaccuracies of the signal models. I this talk, I will highlight ways to measure and compare the two sources of errors and assess how they impact current and future gravitational-wave observations.
