Notes. Columns give the following information: (1) SDSS ID; (2) redshift; (3) SDSS AB magnitudes in the i band; (4) X-ray observatory; (5) observation ID; (6) date of the X-ray observation; (7) net exposure time in ks; (8) net counts in the 0.5–8.0 keV band; (9) Galactic absorption by Kalberla et al. (2005) (in units of 1020 cm-2); and (10) rest-frame 6 μm luminosities from Duras et al. (2017) (in units of Log[L/ erg s-1]). B: BAL quasars according to the modified absorption index (AI1000 > 100; Bruni et al. 2012), which is a more conservative version of the Hall et al. (2002) definition. The detailed analysis of the BAL properties of WISSH quasars will be presented in a forthcoming paper (Bruni et al., in prep.). a Redshifts from the SDSS DR10 catalog. b Redshifts from LBT-LUCI near-IR spectroscopy (Vietri et al., in prep.). † Proprietary data observations.
