Residuals in FWHM for C iv and Hβ versus EW(Fe ii/[O iii]). The Spearman rank correlation coefficient and associated probability that this distribution of points occurs by chance are listed in the upper left-hand corner. The correlation is comparable in significance to that found for Peak(λ1400/C iv), indicating that the correction derived here is an EV1 effect. RL objects are indicated by the solid circles and the open circles indicate RQ objects.
