database, and from a comparison to the photometric redshift distribution were adjusted to maximize the completeness and minimize the number of interlopers at redshift outside the above range. In that work, we also verified that these criteria are almost (although not entirely) equivalent to the original LBG criteria, by reproducing the synthetic UGR magnitudes for the galaxies. However several differences remain, beside the difference in the filter set and the color selection: first of all the LBGs were traditionally selected in the R-band, which is lacking in the GOODS survey, and not in the z-band, as in this work; furthermore LBGs were originally relatively bright galaxies, since the historical criterion used was $R\le 25.5$, while in this work the selection is pushed till the nominal completeness of the GOODS-MUSIC sample (z-band magnitude limit of 26.0). All these result in some differences in the final sample properties, mainly a redshift distribution of galaxies that is slightly wider than in Steidel et al. (2003) sample and possibly a slightly bluer average color (see also Section 4.1 for this point). Objects flagged as AGNs (on the basis of their X-ray emission,and/or mid-IR excess and/or spectral properties) in the GOODS-MUSIC catalog were not included
