The first column provides the mid-time in days after the
GRB. Vega magnitudes are not corrected for Galactic extinction. The upper
limits are \mbox{3$\sigma$} above the background. The data given in the table supersede the corresponding magnitudes reported in de Ugarte Postigo et~al. (\cite{Postigo08}a,b), Rossi et~al. (\cite{Rossia08}a,b), Updike et~al. (\cite{Updike08}a,b), Malesani et~al. (\cite{Malesani08}), and Perley et~al. (\cite{Perley08}).
