The stellar mass-size relation (top panel) and the velocity-size relation (bottom panel) for MASSIV rotating galaxies at z ~ 1.2 (solid, blue line with the 1σ error of the correlation illustrated by the light blue area). The local relation of Dutton et al. (2007, D07) is shown as a short-dashed, black line. We overplot the best-fit relations obtained by (Puech et al. 2008, P08, z ~ 0.6, dotted red line), Bouché et al. (2007), and Cresci et al. (2009) at z ~ 2 (B07, dotted-dashed orange line), and Dutton et al. (2011) using measurements of Förster Schreiber et al. (2009) (FS09, z ~ 2, long-dashed orange line). The symbols are as in Fig. 1.
