The LF at z = 7, obtained using as morphological templates real bright (J < 27.4) candidates at z ~ 7 found in the HUDF (template 3). The magenta circle represents the LF found in the Hawk-I from C10a, while the other symbols indicate the LF in the HUDF and ERS derived adopting different color criteria: our color criteria (red filled circles, criterion C), Bunker et al. (2010) (small filled black triangles, criterion B) and Oesch et al. (2010a) (blue squares, criterion A). The blue points are shifted by −0.1 mag and the black points by +0.1 for clarity. The blue dashed and green dot-dashed lines show the LF at z = 6 of McLure et al. (2009) and Bouwens et al. (2007), respectively.
