| 英文摘要 | Analysis of AstroSat CZTI data showed the detection of a GRB 191025B, which was also detected by Insight-HXMT/HE (Luo Q. et al., GCN #26081), IPN triangulation (Svinkin D. et al., GCN #26086) and Konus-Wind (Kozlova et al., GCN #26089). The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple pulses of emission with the strongest peak at 2019-10-25 18:42:09.0 UT. The measured peak count rate associated with the burst is 449 cts/s above the background in the combined data of four quadrants, with a total of 567 cts. The local mean background count rate was 514 cts/s. Using cumulative rates, we measure a T90 of 6.9 s. It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. CZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR- led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project. |
