TIR LFs for galaxies after rejecting AGN-host galaxies in the inner ( R ⩽ 98′ ≈ 2.6  h ⁻¹ Mpc) region (a) and in the outer ( R > 249′ ≈ 6.5  h ⁻¹ Mpc) region (b). Circles and crosses are for early- and late-type galaxies, respectively, and squares are for the total sample. To sense the change of the slope of the LFs if any, we match the scales of the Y-axis of the two panels.
