英文摘要	Insight-HXMT was taking data normally around the GW trigger time(T0=2019-05-10 02:59:39 UTC). At T0, more than 70% of the LIGOlocalization region was covered by Insight-HXMT without occultationby the Earth.Within T0 +/- 100 s, no significant excess events (SNR > 3 sigma) are found in a search of the Insight-HXMT/HE raw light curves.Assuming the GW counterpart GRB with three typical GRB Band spectral models, two typical duration timescales (1 s, 10 s) from the peak position of the LIGO-Virgo location probability map, the 5-sigma upper-limits fluence (0.2 - 5 MeV, incident energy) are reported below:Band model 1 (alpha=-1.9, beta=-3.7, Ep=70 keV):1 s: 2.4e-07 erg cm^-210 s: 9.1e-07 erg cm^-2Band model 2 (alpha=-1.0, beta=-2.3, Ep=230 keV):1 s: 3.0e-07 erg cm^-210 s: 1.2e-06 erg cm^-2Band model 3 (alpha=-0.0, beta=-1.5, Ep=1000 keV):1 s: 3.0e-07 erg cm^-210 s: 1.3e-06 erg cm^-2All measurements above are made with the CsI detectors operating in theregular mode with the energy range of about 80-800 keV (deposited energy).Only gamma-rays with energy greater than about 200 keV can penetratethe spacecraft and leave signals in the CsI detectors installed insideof the spacecraft.Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
