“Voyager” era (late 2020s) detection and localization for the HLV network (left) and the full gravitational-wave detector network (right) as a function of time before merger for a fiducial 1.4–1.4 ﹩{M}_{\odot }﹩ BNS merger. (Top) The sky-averaged detection range for the idealized search and PyCBC Live operating at a false-alarm rate of once per year. (Middle) The upper limit on the localization sky area and source distance, respectively, for detectable sources. Sky areas are quoted at the 90% credible level. (Bottom) The detection rate of all sources (black) and those that also have a sky localization less than 1000 deg² (blue), 100 deg² (orange), 10 deg² (green), or 1 deg² at a 90% (solid), 50% (dashed), and 25% credible level (dotted).
