$\begin{figure} \par\includegraphics[angle=-90,width=8.3cm,clip]{4172f1co.ps} \end{figure}$ Figure 1: XRT image of XRF 050406, obtained from the total $\sim$ 163 ks PC mode data. The field is centred on the 3 $\hbox {$^\prime $ }$ radius BAT error circle. Also shown is the XRT 4 $.\!\!^{\prime\prime}$ 2 error circle, as well as the Magellan (Berger et al. 2005a) and UVOT (Rol et al. 2005) optical counterpart positions; the optical points are so close they cannot be distinguished on this scale. S2 is a serendipitous source located at RA(J2000 $)=02^{\rm h} 17^{\rm m} 52\hbox{$.\!\!^{\rm s}$ }9$ , Dec(J2000 $)=-50^{\circ} 10\hbox{$^\prime$ }36\hbox{$.\!\!^{\prime\prime}$ }1$ .

$\begin{figure} \par\includegraphics[width=12cm]{4172f2co.ps} \end{figure}$ Figure 2: X-ray light curve of the XRF 050406 afterglow in the 0.2-10 keV energy band. The curve is background-subtracted and the time is referred to the BAT trigger, 2005 Apr. 06 at 15:58:48.4 UT (Parsons et al. 2005). The last point after 10⁶ s is a 3- $\sigma$ upper limit. Inset: details of the first $\sim$ 1000 s, which include data in all XRT modes. The (yellow) diamonds represent LrPD mode data taken during the latter portion of the slewing phase; the (cyan) triangle is the initial IM point (84 s after the trigger, see Table 1), the downward-pointing arrow is a LrPD limit (pointing, 91 s after the trigger), the (blue) circles are WT mode data (starting from 92 s after the trigger), and the (red) squares are PC mode data (starting from 99 s after the trigger). The data have been corrected for pile-up (where appropriate) and PSF losses. The solid (red) line represents the best-fit broken power-law model to the light curve (excluding the flare).
