Fig. 1.


Reduced spectra of two X-ray selected type-2 AGNs in the COSMOS field (ID: 05162 and 10690) obtained with FOCAS, after adopting 4 pixel binning in wavelength direction. Their two-dimensional spectra with a 2″̣1 section are shown at the top, respectively. Red vertical lines indicate the central wavelengths of rest-frame UV emission lines, i.e., Lyλ, N Vλ1240, C IVλ1549, He IIλ1640, and C IIIλ1909. The gray line in the top panel is an arbitrary spectrum with five times the flux for recognising relatively weak emission lines.
