    PR # 31540                                                                   
     As part of a long-term theoretical and observational study  aiming at       
      determining the processes shaping the soft X-ray to gamma-ray spectr       
     a of AGNs we intended to observe  four Seyferts, Mrk 478, E1615+061,        
     NGC 3227, and NGC 7172 to supplement existing data samples.  The high       
      resolution capabilities of ASCA allows the best  determination so fa       
     r of the 0.1-10 keV spectrum. In particular, ASCA has already been ab       
     le to resolve reflected  Fe-line into neutral H-like, and He-like com       
     ponents, resolve other reflected  soft X-ray K-lines, and to resolve        
     the complex absorption due to warm absorbers. This allows a much more       
      accurate determination of the various spectral components.  ESA reco       
     mmended 20 ks for NGC 7172, a Seyfert 2 whose Ginga spectrum shows st       
    rong photoelectric absorption.
