$\begin{figure} \par\includegraphics[angle=-90,width=14.4cm,clip]{4616fig1.eps}\end{figure}$ Figure 1: 2-30 keV RXTE-PCA light curve of 4U 1538-52 between July 31 and August 7, 2003. Two 26 s binned $\sim$ 3 ks samples of this light curve corresponding to single RXTE orbits are presented on the upper left and the upper right.

$\begin{figure} \par\includegraphics[angle=-90,width=8.4cm,clip]{4616fig3.ps}\end{figure}$ Figure 3: The phase residuals of orbital epoch for 4U 1538-52. The orbital phases are estimated relative the constant orbital period $(T_{\pi/2}-n\langle P_{\rm orbit}\rangle -\langle T_{\pi/2}-n\langle P_{\rm orbit}\rangle \rangle )$ , where n is the orbital cycle number (see Table 2). The rightmost point corresponds to the most recent RXTE observation of ID 80016.
