  Title: COMPLETING AN UNBIASED SEYFERT 2 SAMPLE : NGC3081 AND MKN573                    


Abstract:
 We propose 35 and 50 Ks observations of the two Seyfert 2 galaxies, NGC 3081 and MKN
 573. These two observations, combined with others in the ASCA archive, will complete
 a flux-limited sample of 6 type 2 Seyfert galaxies selected on the basis of the
 least biased parameter, the [OIII]5007 line flux. This sample will provide the best
 feasible basis for estimates of the distribution of column density, continuum slope
 and Fe K$_{\alpha}$ EW in Seyfert 2. These distributions are essential for the study
 of AGN unification schemes, and to evaluate the contribution of Seyfert 2s to the X-ray background.
