    PR # 32191                                                                   
     PSPC observations of AGN showed strong soft X-ray features which            
     could be interpreted as absorption edges with optical depths                
     typically 0.1-0.5 and energies associated with O VII-O VIII. Such           
     features have been  interpreted as evidence for large amounts of            
     ionized circumnuclear material.  Observations to date indicated that        
     one source, NGC3783, was distinct in having an absorption  feature of       
     optical depth of 2.5, considerably larger than that observed in other       
     AGN. We have now discovered that the AGN 3A0557 and 3C445 are similar       
     to NGC3783. These sources are excellent candidates for a detailed           
     study of the detailed conditions of the ionized absorber in AGN.
