Comparison between R_last and R_1/2,star radii computed as the size of our ionized gas maps with a confidence level larger than 2σ and the half-light radius of the stellar continuum measured on the observed I-band best-seeing CFHTLS images, respectively. Within the errors, both rotators (top panel, blue circle) and non-rotators (bottom panel, red square) agree with the expected statistical trend R_last = 1.9 × R_1/2,star found by Persic & Salucci (1991, PS91) plotted with a black dotted line. The blue/red solid lines are the best-fit relation found for the rotators/non-rotating galaxies (dashed lines show the total scatter of the correlations). The empty symbols show galaxies detected with a low S/N (3 ≤ S/N ≤ 4.5).
