Gaussian line scans for intervals of 0.7 second durations. The best-fit results for the radii expressed in km for a source distance of 8 kpc are obtained with the spectra optimally binned. The best-fit C-STAT and the number of degrees of freedom are given in parenthesis. The lines reported in Strohmayer et al. (2019) are shown as vertical black dash-dotted lines for four of the first five bursts. The position of the local extrema found in the scan are shown with the vertical red lines.
