LIGO Document P1900218-v2
- To facilitate proposals by astronomers for observing time we present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years. We show the sensitivity prospects for the third (O3), fourth (O4) and fifth observing (O5) runs. We present the target strain sensitivities as a function of frequency for Advanced LIGO, Advanced Virgo and KAGRA, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors, and the achievable range for binary neutron star, neutron star–black hole, binary black hole, and unmodeled signals. We show the planned observing timeline and sensitivity evolution of the detectors. The updated version of the more complete "Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo" (Abbott et al, 2018) is a work in progress, and will include estimates of the network's ability to localize gravitational-wave transient signals (as sky-localization probability area, distance and volume), and to detect binary neutron star, neutron star–black hole, and binary black hole systems (as number of detections per calendar year of running).
