Fluxes of emission lines in the CoCoA group 2. The left graph shows CoCoA group 2 fluxes with 3σ error bars for 87 Seyfert-1s. The right graph shows CoCoA group 2 fluxes for 87 Seyfert-2s, selected to match in redshift and Balmer decrement Hα/Hβ to the Seyfert-1s, Balmer lines excluded. The CoCoA group 2 consists of the same lines in both cases. Seyfert-1s appear however one order of magnitude more luminous in the [O iii] lines and [O i]6302 than their Seyfert-2 counterparts. The fluxes are in units of 10^-17 erg/s/cm².
