Notes. In Cols. 3−5, the line luminosities are reported for the intermediate (i) with FWHM = 1000−3000 km s-1, broad (b) with FWHM = 4000−5000 km s-1; and very broad (vb) with FWHM> 9000 km s-1 components (defined in Sect. 2.2). Restframe nominal wavelengths are in Å, luminosities are in units of 1041 erg s-1. Instruments: 1: XMM-Newton-EPIC-PN, 2: XMM-Newton-RGS, 3: FUSE, 4: HST-COS, 5: XMM-Newton-OM.
