Extended Data Fig. 4: Spectral lag calculation.
From: A peculiarly short-duration gamma-ray burst from massive star core collapse
Spectral lag calculation. a, light curves in different energy bands(10-20 keV ~ 300-500 keV) which are used to calculate lags. b, energy dependent spectral lag between the lowest energy(10-20 keV) band and any higher energy band. All error bars represent 1-σ uncertainties.
