^a Apparent B Johnson magnitude corrected because of Galactic absorption. The value of HE 0436-3709 referes to the b Strömgren magnitude. ^b Redshift, with uncertainty in parentheses. ^c Lines used for redshift calculations: 1: H $\beta$ , 2: [ OIII] $\lambda$ 5007. 3: [O III] $\lambda$ 4959. ^d Absolute B magnitude, computed for H₀=70 km s^-1 Mpc^-1, $\Omega_{\rm M} = 0.3$ , $\Omega_{\Lambda} = 0.7$ , and k-correction spectral index a=0.6. ^e Decimal logarithm of the specific flux ratio at 6 cm and 4400 Å (effective wavelength of the B band). Upper limits are from the NVSS ( $\approx$ 2.5 mJy), and would place all undetected sources in the RQ domain. ^f Date refers to time at start of exposure. ^g Photometric band. ^h Detector Integration Time (DIT) of ISAAC, in seconds. ⁱ Number of exposures with integration time equal to DIT. ^j Airmass at start and end of exposure. ^k S/N at continuum level in the proximity of H $\beta$ . Two values are reported in case of different S/N on the blue and red side of H $\beta$ (blue side first). The S/N value is with N estimated at a $2\sigma$ confidence level i.e., 2 times the rms.
