Notes. Emission-line fluxes are reported both as observed and (between square brackets) corrected for the intervening Galactic absorption E(B − V)Gal along the object line of sight (from Schlegel et al. 1998). Line fluxes are in units of 10-15 erg cm-2 s-1, whereas X-ray luminosities are in units of 1043 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). The typical error in the redshift measurement is ± 0.001 but for the spectrum of IGR J12319 − 0749, for which an uncertainty of ± 0.01 can be assumed.
