Figure 1:
The "IT effect'': neutral iron EW against 2-10 keV X-ray luminosity of the objects in our catalogue. The anti-correlation between the two parameters is shown as the best fit line, whose analytical expression is reported on the top. The broken lines represent the combined error on the slope and normalization of the best fit. The different symbols refers to the classification of the objects, on the basis of their absolute magnitude and H
FWHM: NLSY, narrow-line Seyfert 1; BLSY, broad-line Seyfert 1; NCSY, not-classified Seyfert 1 (no H
FWHM measure available); NLQ, narrow-line quasar; BLQ, broad-line quasar; NCQ, not-classified quasar (no H
FWHM measure available). See text for details. |
