Notes. Here we report the effects of each cut separately to highlight its effect, hence the fractions reported in the table do not add to 100%. The most impacting cuts are those on 
and on NB excess significance. The number of sources passing all these conditions, for each NB, produce our final samples of LAE candidates and is shown in the last column to the right. These partial samples are likely to be highly contaminated by interlopers showing reliable NB excess. Table 4 shows a summary of the sample contamination and the final number of selected sources.
