Corresponding afterglow lightcurves of Figure 4. The dashed lines represent the flux from Region 3, while the dotted lines are emissions from Region 2. The total flux is shown as the solid lines. In the calculations, the optical band is taken as  Hz and the X-ray band is taken as 0.3–10 keV. The red dashed vertical line marks the position of .
