Normalized flux density in the R‐band light curve of the afterglow of GRB 010921, as constrained by the upper limits from the LOTIS telescope, and the measurements from the SDSS PT, the Super‐LOTIS, the Tautenburg Schmidt, and the USNOFS telescopes. The fluxes in the different filters have been transformed to the R band assuming a power‐law spectrum of index ﹩\beta =-2.3﹩ (Price et al. 2001).
