 $^{{a}}$  Apparent B Johnson magnitude corrected because of Galactic absorption. The value of HE 0436$-$3709 referes to the b Str\"omgren magnitude. 
 $^{{b}}$ Redshift, with uncertainty in parentheses.
 $^{{c}}$  Lines used for redshift calculations: 1: \hb, 2: \oiii. 3: [\ion{O}{iii}]\l4959. 
$^{{d}}$ Absolute $B$~magnitude, computed for $H_0=70$~\kms~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~\AA\ (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 \hb. Two values are reported in case of different
$S/N$\  on the blue and red side of \hb\ (blue side first). The $S/N$\ value is with 
$N$ estimated at a $2 \sigma$\
confidence level i.e., 2~times the rms.
