GWFish: A simulation software to evaluate parameter-estimation capabilities of gravitational-wave detector networks

Understand

An important step in the planning of future gravitational-wave (GW) detectors and of the networks they will form is the estimation of their detection and parameter-estimation capabilities, which is the basis of science-case studies.

• Several future GW detectors have been proposed or are under development, which might also operate and observe in parallel.
• These detectors include terrestrial, lunar, and space-borne detectors.
• In this paper, we present GWFish, a new software to simulate GW detector networks and to calculate measurement uncertainties based on the Fisher-matrix approximation.
