Table 3: Observed and simulated surface densities of objects (in arcmin^-2) recovered using the selection box (Eq. (1)), based on simulations described in Sect. 3.3 and observations in the CFDF-14 hr field. We also estimate the fraction of Lyman-break galaxies (LBG) recovered using this selection box from the total galaxy population in this redshift range. Additionally, we present the fraction of contaminants within this selection box by interlopers (lower-redshift galaxies) outside our redshift range (2.9<z<3.4) and by interlopers with z<2 and by stars.
