**Table 3:** Comparison of different mass estimates. We present here masses obtained from broad band (3-100 keV) spectral fitting (Col. 2) and narrow band spectral fitting - our model (Cols. 3 and 4), work of Ramsay 2000 (Col. 5), work of Cropper et al. 1999 (Col. 6), and work of Ezucka & Ishida 1999 (Col. 7).
