Notes. Summary of the most important properties of the SED fits of the most likely candidates. The redshifts of B2 and D3 were fixed to the spectroscopically measured redshift in the SED fit. The impact parameters, θ, were calculated from Table 4, assuming either z = 0.6915, 1.430, or 3.096. The luminosities were computed using the results by Dahlen et al. (2005) and Steidel et al. (1999) on LFs; the knee of the luminosity functions L_∗ is at M_B,  ∗ =  −21.43 M_B =  −21.60 and m_R = 24.48 mag at z = 0.692, 1.4288 and 3.096, respectively. We note that the stellar mass and its uncertainty were derived assuming a Chabrier IMF (Chabrier et al. 2000, see also Sect. 2.3 for more details on the SED fit).
