Comparison of Eddington ratios estimated by the Hβ line with that by the C ivλ1549 line. Red, gray, and yellow circles are the same as those in Fig. 6. The one-to-one relation is indicated by the dashed line. Eddington ratios averaged from Hβ and C ivλ1549 lines are given as histograms in the small bottom panel. The red- and yellow-filled histograms show averaged Eddington ratios of our N-loud quasars and SDSS normal ones at log λL1350< 46.5 from Shen & Liu (2012), respectively.
