and the CALET collaboration:
The long-duration GRB 170510A (Roberts et al., GCN Circ. 21085;
Bissaldi et al., GCN Circ. 21080; Svinkin et al. GCN Circ. 21090;
Sharma et al. GCN Circ. 21093; INTEGRAL SPI-ACS trigger #7841)
triggered the CALET Gamma-ray Burst Monitor (CGBM) at 05:12:23.19 on
10 May 2017. The burst signal was seen by all CGBM instruments.
The light curve of the SGM shows multiple peaks. The emission
starts from T+5 sec, peaks at T+25 sec and ends at T+35 sec.
The T90 duration measured by the SGM data is 24.9 +- 1.0 sec (40-1000 keV).
The light curve is available at
The CALET data used in this analysis are provided by the Waseda
CALET Operation Center located at the Waseda University.
