Here we present the uniform light curve dataset for the afterglow of GW170817. This online dataset will be continuously updated as new measurements become available. For more details see Makhatini et al. (2020).

Upper panel: The panchromatic (radio, optical and X-ray) afterglow light curve of GW170817, color coded according to the observing frequency, up to 940 days post-merger (all data points have 1-sigma errorbars as presented in Makhatini et al. (2020) Table 1; upper limits are not shown here) using the uniform dataset presented here. The light curve is scaled to 3 GHz using the best-fit spectral index (-0.569) derived from the MCMC power-law fitting (see Makhatini et al. 2020). Lower panel: The averaged light curve (blue data points) shows a general trend consistent with power-law rise and decline. In grey are the same data points as shown in the upper panel.
