Intrinsic emission-line LFs. From top to bottom and from left to right: Hα, Hβ, [O II], [O III], [N II], and [S II] intrinsic (i.e., dust corrected) luminosity functions of the main-ELG sample (full black dots). The contribution of ELGs classified in different ways are shown by empty colored markers, with colors as indicated in the legend. We overplot the Saunders fits as thick black lines; the parameters are tabulated in Table 5 and were obtained considering only the points above the luminosity completeness threshold established in Sec. 2.5. For those lines having the lower completeness limit in the L range of the figure, we highlight with a yellow shade the region of incompleteness, where our LFs cannot be trusted. The error bars are computed from 70 jackknife resamplings.
