Notes. EWs are expressed in Å, line fluxes are in units of 10-15 erg cm-2 s-1, whereas X-ray luminosities are in units of 1035 erg s-1 and the reference band (between round brackets) is expressed in keV. In the last column, the upper-case letter indicates the satellite and/or the instrument with which the corresponding X-ray flux measurement was obtained (see text).
