Summary of TDR ($D_{90}^{\mathrm{TDR}}$) values for all the GRBs detected during the first three LVK observing runs. The TDR is reported by default using a SNR cut at 10. The comparison with PyGRB exclusion distances is done for BNS systems and adopting an SNR cut of 9. $D_{90}^{\mathrm{TDR}}$ values for BNS are computed assuming $m_1=m_2=1.4\,M_\odot$ and for NSBH $m_{\mathrm{BH}}=10\,M_\odot$, $m_\mathrm{NS}=1.4\,M_\odot$. The $D_{90}^{\mathrm{TDR}}$ values for NSBH show the average obtained assuming SFHo and DD2 equation of states. The inclination angle of the binary is assumed to be isotropically distributed between 0 and 30 deg. A dash indicates that no PyGRB exclusion distance is available, since the GRB is classified as long. If the set of IFOs used in our analysis differs from that used in LVK targeted searches, the latter is reported in brackets. GRB170817529 corresponds to GRB170817A, detected in coincidence with GW170817

针对LIGO-Virgo-KAGRA(LVK)前三次观测运行期间探测到的所有伽马射线暴(Gamma-Ray Burst, GRB),汇总其TDR的$D_{90}^{mathrm{TDR}}$值。默认情况下,TDR采用信噪比(Signal-to-Noise Ratio, SNR)阈值10进行计算。针对双中子星(Binary Neutron Star, BNS)系统,我们采用信噪比阈值9,与PyGRB排除距离进行对比。双中子星的$D_{90}^{mathrm{TDR}}$值假设$m_1=m_2=1.4,M_odot$计算得到;中子星-黑洞(Neutron Star-Black Hole, NSBH)系统的$D_{90}^{mathrm{TDR}}$值则采用$m_{mathrm{BH}}=10,M_odot$、$m_{mathrm{NS}}=1.4,M_odot$的参数设定。中子星-黑洞系统的$D_{90}^{mathrm{TDR}}$值为采用SFHo与DD2物态方程(Equation of State, EOS)计算得到的平均值。双星轨道倾角假设为0至30度间的各向同性分布。破折号表示无可用的PyGRB排除距离,原因是该伽马射线暴被归类为长暴。若本次分析所用的干涉仪(Interferometer, IFO)组合与LVK靶向搜索所用的组合不同,则将后者标注在方括号内。GRB170817529对应与GW170817成协探测到的GRB170817A。
