WHAN diagram of galaxies of Cl0024. 131 galaxies of the 173 ELGs are presented in this diagram. 42 galaxies are not present because they do not have a good estimation of [N II]λ6583 flux or are BLAGN. The prescriptions of Ho et al. (1997), Kewley et al. (2001) and Stasińska et al. (2006) are shown in the diagram. The symbols are the same as in Fig. 5 and are described in the upper-right legend. We also show the galaxies that could not be classified in the BPT diagram with pink-filled symbols. The median of the uncertainty bars are shown in the lower-right part of the figure.
