Notes.

(a)

Source identification numbers in agreement with those listed in the first column of Table 1.

(b)

Black hole mass estimated using SE virial relation in Eq. (5) when possible, otherwise, the value provided here is the one available in literature (see references for full details). The uncertainties we report do not include the systematic uncertainties intrinsic to the MBH estimators.
