\caption{\label{t2}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).}.
