An ionized absorber based on that of Done et al. (1992, ApJ 395, 275) and developed by Magdziarz & Zdziarski (1995, MNRAS 273, 837). See also Zdziarski et al. (1995, ApJ 438, L63). Photoionization rates are from Reilman & Manson (1979, ApJS 40, 815), who employ the Hartree-Slater approximation (accurate to about 5%), and recombination rates are from Shull & van Steenberg (1982, ApJS 48, 95). The cross sections are extrapolated with above 5 keV. The abundances are set up by the command abund. Send questions or comments to aaz@camk.edu.pl
