Faber-Jackson relation for the early-type galaxies in our sample. The black points represent the galaxies with z < 0.35, and the open red diamonds are the objects with z > 0.35. The dashed black line is the local relation used by Fritz et al. (2009a), and the dot-dashed red line is the fit to their distant sample (0.2 < z < 0.75). The solid red line is the weighted fit to our high-redshift sample.
