The ASCA and BeppoSAX spectra of the Circinus Galaxy and NGCÂ 1068 are analysed and compared with photoionization models based on cloudy .
In the case of Circinus , a single , mildly ionized reflector can account for the line spectrum , while in NGCÂ 1068 at least three different reflectors ( with different ionization states ) are needed .
We suggest that the reflector in Circinus , and the low ionized one in NGCÂ 1068 are the inner and visible part of the material responsible for the X–ray absorption .
With this assumption , we estimate for the inner radius of the absorber a value of 0.2 pc for Circinus and of a few parsecs for NGCÂ 1068 .
