We have observed a dozen bright Seyfert 2's selected by their [OIII]λ5007 emission line flux (Ueno et al 1996, Awaki et al 1996). We chose this to be a flux-limited sample free from X-ray selection effects such as intrinsic absorbing columns (NH) and differences in viewing angle (Mulchaey et al 1994). Is it genuinely free from these selection effects? To investigate this, we compare the [OIII] luminosity of various Seyfert 2 galaxies. For this paper, we assume the Hubble constant to be H0 = 50km s−1 Mpc−1.
