Pseudo-EW measurement for the candidates with spectra (black dots). Two measurements for object #30, separated by about a month, are additionally denoted with open circles, and the objects with other signatures of youth (Na I doublet, X-ray detection or IR-excess) with orange crosses. The criteria separating the accretors from the non-accreting sources are shown by a dashed line (Barrado y Navascués & Martín 2003) and a dotted (Fang et al. 2009) line.
