Table 2.

Correlations between the different Fe II line ratios and some physical parameters.

		FWHM Fe II_cons	log R_Edd
$\frac{{Fe II}_{cons}}{{UV Fe II}_{60}}$ $\frac{\mathrm{Fe~II}_{\mathrm{cons}}}{\mathrm{UV~Fe~II}_{60}}$	r	−0.22	0.21
	P	8E-4	0.001

$\frac{{Fe II}_{cons} G}{{UV Fe II}_{60}}$ $\frac{\mathrm{Fe~II}_{\mathrm{cons}} G}{\mathrm{UV~Fe~II}_{60}}$	r	−0.31	0.25
	P	2E-6	2E-4

$\frac{{Fe II}_{incons}}{{UV Fe II}_{60}}$ $\frac{\mathrm{Fe~II}_{\mathrm{incons}}}{\mathrm{UV~Fe~II}_{60} }$	r	−0.40	0.35
	P	4E-10	6E-8

$\frac{{Fe II}_{incons}}{{Fe II}_{cons}}$ $\frac{\mathrm{Fe~II}_{\mathrm{incons}}}{\mathrm{Fe~II}_{\mathrm{cons}}}$	r	−0.43	0.37
	P	3E-11	1E-8

Notes. The correlations are done for the subsample of 220 objects used in the PCA (with present UV and optical Fe II lines and FWHM Fe II < 5000 km/s). The table contains Spearman coefficients of correlation (r) and P-values.
