The LF at z = 7, obtained using as morphological templates the stacking of the faint candidates at z ~ 7 found in the J band image of the HUDF (template 5) and the C color criterion. The LF is computed using ERS and HUDF fields together (red filled squares, G10). The green filled squares show the LF obtained with the same color criterion C but using the HUDF-1095 candidate as input for the simulations (template 4). These data have been complemented with the results of Ouchi et al. (2009) (O09), Bouwens et al. (2010b) (B10) and C10b. The lower dashed magenta line is the best fit to all the observed points related to the template 5, the upper dashed magenta line is the best fit related to the template 4, while the black solid line shows the Hawk-I result of C10a. The blue dashed and green dot-dashed lines show the LF at z = 6 of McLure et al. (2009) (M09) and Bouwens et al. (2007) (B07), respectively.
