Description:
Catalog of type-2 AGN optically selected from the zCOSMOS survey using
the diagnostic diagrams. The sample spans the redshift range
0.15<z<0.92 and the luminosity range
105.5L☉<L([OIII])<109.1L☉.

Note (1): Quality Flag defined as 3 digits (ab.c).
* Unit digit (b in ab.c) represents the confidence class:

Flag Description Spectroscopic Photo-z consistency
verification within dz=0.08(1+z)
-----------------------------------------------------------------------------
4 Very secure redshift,
beautiful redshift >99.5% 97%
3 Secure redshift >99.5% 97%
9 One line redshift 95% 84%-95% (after
(best guess) (after correction) correction with photo-z)
2 Probable redshift 92% 93%
1 Insecure redshift 70% 72%
0 Unidentified spectrum
-----------------------------------------------------------------------------
* the decimal (.c) represents the Spectroscopic/photometric consistency:
---------------------------------------------------------------------------
.5 Spectroscopic redshift consistent within 0.08(1+z) of the
photometric redshift, both for galaxies, stars and AGN.
.4 No photometric redshift available, includes all spectroscopic
AGN and stars
.3 Special case for Class 18 and 9: Consistent with photo-z only
after the redshift changed to the alternate redshift,
a switch which is then applied
.1 Spectroscopic and photometric redshifts are not consistent at
the level of 0.08(1+z)
---------------------------------------------------------------------------
* the tens (a in ab.c) is
-----------------------------
0 = Galaxies and stars
1 (+10) = Broad line AGN
2 (+20) = Secondary targets
