Ionized Disc Models of MCG-6-30-15
  Ionized reflection is one of the possible mechanisms proposed to explain the small short-timescale variability of the MCG-6-30-15 Fe K line. In this contribution, we show fits of the Ross & Fabian ionized reflection models to the 325 ks XMM-Newton observation of MCG--6-30-15. It is found that the spectrum above 2.5 keV can be fitted with a combination of an ionized reflector from 5 r_g and a neutral reprocessor beyond about 70 r_g. The ionization parameter of the inner reflector increases as the source brightens.
