The model consists of a power law with a Gaussian for the Fe K$\alpha$~line, modified by warm and cold absorption. The cold absorption column is denoted by \nH, which is in excess of the Galactic column of $1.85\times 10^{20}$~\psqcm. Tim Kallman's XSTAR grid tables (``grid~25'') with the turbulent velocity of 200~km~s$^{-1}$ is adopted for the warm absorber modelling.} \end{table}
