Modeled flux tube contributions to E_1D(k) (dashed and dotted curves) based on two somewhat different versions of the flux tube distributions derived in Stenflo (2010). When the MTF of the Hinode telescope, T(k), is applied, the two curves get truncated near the Hinode resolution limit and become the dash-triple-dot and dash-dotted curves. The lower of the two solid curves is identical to the solid curve in Fig. 4. When this curve is divided by T(k) to compensate for the MTF quenching, the upper solid curve is obtained.
