Light curve of the X-ray (top panel) and optical/NIR (middle panel) afterglow of GRB 080413B. Bands are offset by g′ + 2,r′ + 1.5,i′ + 1,z′ + 0.5,H − 0.5,K_s − 1 mag, and REM data R_R and H_R have offsets corresponding to GROND data. The bottom panel shows residuals to the combined light curve fit. Shown data are corrected for the Galactic foreground extinction and transformed into AB magnitudes. Upper limits are not shown for better clarity. Gray regions show the time intervals where SEDs are reported (Fig. 4).
