Table 1: Best-fits to the 0.5-10 keV XMM-Newton PN persistent emission spectra of X1254-690 using a disk-blackbody model with an inner temperature $KT_{\rm in}$ and normalization k given by $(R_{\rm in}/d)^2$ where $R_{\rm in}$ in the inner radius in km and d the distance in units of 10 kpc and a power-law with a photon index, $\alpha $ together with an emission and two absorption lines.
