GRBs with optical afterglows

This table is completely outdated, and presently not foreseen to be updated. For an updated list of all GRBs until end of 2004 see the following two references:

This table provides a summary of the power law indices of the temporal decay of the optical afterglow emission in GRBs. Links have been added for each GRB to the corresponding "devoted" GRB page (under the GRB name), the reference, mostly astro-ph or GCN (under the decay index), as well as to the GIF figure when available (third column).

⁽¹⁾ If the light contribution of the supernova component is taken out, then the resulting decay slopes are steeper (appended in the fourth column) than given in the second column which i.g. represents the mean decay law over all times of the GRB afterglow light curve.
⁽²⁾ In GRB 980326 the SN bump occurred late enough to not affect the fit for the first day's decay law.
