  Title: WHERE IS THE ABSORBER SEEN IN THE SOFT X-RAY SPECTRUM OF THE BL LAC OBJECT PKS 0548-322 ?


Abstract:
 We propose to observe the BL Lac object PKS 0548-322 which exhibit three absorption
 features in its soft X-ray spectrum observed in the ASCA PV observation phase. To
 determine its distance from the emission region and its density, follow up
 observation under different luminosity is needed. In comparison with the results
 obtained with Einstein observatory, it is suggested that depths of one of the
 absorption feature may have changed in different luminosity, but still we need to
 determine the continuum tightly with the broader band spectrometer onboard ASCA. It
 is interesting in the point of view of unified scheme of AGN including radio galaxies.
