$\begin{figure} \par\includegraphics[angle=-90,width=11.5cm,clip]{050724_lc.ps} \end{figure}$ Figure 1: X-ray light curve of GRB 050724. Count rates have been converted into 0.2-10 keV unabsorbed flux after spectral modelling (see text). Times have been converted to the GRB progenitor reference time. Open circles mark BAT data (as well as $3\sigma$ upper limits) extrapolated to the 0.2-10 keV energy band; filled circles mark XRT-WT data and open squares XRT-PC data, respectively. The continuous line represents the best fit model obtained with four Gaussians and a triple power law (see text). Dashed lines indicate WT mode time intervals selected for spectral analysis. Dotted lines indicate time intervals used for spectral analysis in PC mode.

$\begin{figure} \par\includegraphics[angle=-90,width=7.5cm,clip]{050724_hardn.ps} \end{figure}$ Figure 2: Hardness ratio light curve. The ratio is between 1-10 keV to 0.2-1 keV. Time has been corrected for redshift time dilation. Filled circles mark XRT WT data, open squares XRT PC data, respectively. The dashed line indicates the mean value of the data starting from 370 s from the burst trigger (rest frame).
