Stellar angular momentum (λ_R) aperture relations for different aperture sizes. Top and middle panels: relation between λ_Re with the values of smaller/larger apertures 0.5 R_e and 2 R_e. Bottom panel: comparison of λ_Re with that computed with a 1D long-slit along the major axis of the galaxies. The dashed lines indicate the biweight mean values while dotted lines indicate the standard deviation.
