For all filters except~$R_{\rm C}$, $\lambda$ is from Poole et~al. (\cite{Poole2008}). Data refer to $t=0.27$~days. A redshift of $z=3.773$ was assumed. The values have been corrected for Galactic extinction. The fluxes have been calculated assuming the conversion factors from Bessell (\cite{Bessell1979}) and Poole et~al. (\cite{Poole2008}). \end{table}
