Abstract:: Comparison of 90% credible sky localization area for BNS, BBH and NSBH detections in O3 between with and without KAGRA for Ndet=2, 3, 4 cases.
O3 sensitivities assumed as 120Mpc(H,L), 60Mpc(V), and 25Mpc(K).
Original simulation by L.Singer and data were available at:
https://git.ligo.org/publications/detectors/obs-scenarios-2019/tree/master/Simulations

New simulations with 15Mpc(K) and 8Mpc(K) are also added.
Simulations are made with GPU-accelerated Parameter Estimation (GPE) with nested sampling MCMC (JGW-G1808212).

KAGRA sensitivity curves are from JGW-T1809078.

Data and scripts are also shared to LV at:

Event example is BNS (1.25,1.44) at 46 Mpc, cos(theta_JN)=-0.41, spin(z)=0.03,-0.01

These works are done by Y.J. Huang (NTU) and SH and GPU farm management is supported by C.Y. Lin (NCHC).
