Extended Data Fig. 1: The WXT spectrum in the time interval of T90.
From: A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
a, The WXT observed spectrum and the predicted best-fit absorbed power-law model. Data are presented as the count rate spectrum with 1σ uncertainties. b, Best-fit values of photon index and intrinsic absorption Nint and the 1σ, 2σ confidence contours. c, The spectral energy distribution. Data are presented as the energy flux density with 1σ uncertainties. The upper limits displayed in brown and green represent those of Konus Wind and Swift/BAT, respectively.
