Notes.

^(a)

GROND optical and near-infrared data were extended with data collected from GCNs and refereed publications. The magnitudes were, if necessary, converted to the AB system.

^(b)

The XRT light curve is also consistent with the model for the NIR/optical afterglow (see Fig. B.2).

^(c)

We used the temporal decay slope as derived from the NIRI K band data to re-scale the NIRI J, H, and K-band observation to a common reference time (see Fig. B.7).
