$^a$  Number of LAEs in the field. In the fields of BRI~1346--0275 and Q~2138--4427 two foreground emission line systems have been excluded from this sample.\\
$^b$  Number of confirmed LAEs in the field.\\
$^c$  Number of candidates not spectroscopically confirmed.\\
$^d$ Lower limit luminosity for those candidates that are detected with a significance of at least $1\sigma$ in the total magnitude.
