The Swift GRB 201013A (Page et al., GCN Circ. 28607, Laha et al.,
GCN Circ. 28614; https://gcn.gsfc.nasa.gov/other/201013A.gcn3)
triggered the CALET Gamma-ray Burst Monitor (CGBM) at 03:46:29.773 UTC
on 13 October 2020 (http://cgbm.calet.jp/cgbm_trigger/flight/1286595863/).
The burst signal was seen by all CGBM detectors.

The burst light curve shows a double-peaked structure which starts
at T+0.5 sec and ends at T+7.5 sec. The T90 and T50 durations measured
by the SGM data are 6.4 +- 0.4 sec and 1.9 +- 0.6 sec (40-1000 keV),
respectively.

The ground processed 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.
