\tablefoot{Column 1 gives the orbital phase, Cols. 2--5 show the spectral model, the hydrogen column density $N_{\rm H}$, the best-fitted photon index or temperature, and the reduced $\chi^{2}$ together with degrees of freedom. Cols. 6--7 list the unabsorbed X-ray flux and luminosity in the $0.3{-}8.0$ keV energy range. Quoted errors indicate the 68\% confidence level for one parameter of interest. \\
\tablefootmark{(a)} PL $=$ power law; TB $=$ thermal bremsstrahlung.
\tablefootmark{(b)} In units of $10^{21}$~cm$^{-2}$.
\tablefootmark{(c)} Unabsorbed X-ray flux in units of $10^{-14}$~erg~cm$^{-2}$~s$^{-1}$ and in the energy range of 0.3--8.0 keV.
