Extended Data Fig. 3: Deriving the transverse velocity from a light curve.
From: A planetary collision afterglow and transit of the resultant debris cloud
a, ASAS-SN g′ photometry is shown in units of normalized flux. Straight-line fits (light-blue lines) are made to the photometry in the regions indicated by the light-grey vertical lines. b, Gradient of the light curve as a function of time. c, Transverse velocity derived from the light curve and the gradient of the light curve. Error bars are shown at 1σ confidence.
