Morphological classification of our M_★ > 10¹⁰ M_⊙ SFGs measured on their HST i-band images. Circles in the left panel are the Gini and M20 coefficient measured on HST i-band images of each individual galaxy, while the right panel shows the Gini and M20 coefficient measured for the stacked images of the different stellar mass and ∆MS bin. Orange, pink, green, and dark blue show SBs (∆MS > 0.7) at 10¹¹ ≤ M_★/M_⊙ < 10¹², SBs at 10^10.5 < M_★/M_⊙ < 10¹¹, SBs at 10¹⁰ < M_★/M_⊙ < 10¹⁰⁵, and M_★> 10¹⁰ M_⊙ SFGs without SBs (∆MS < 0.7), respectively. Stars in the left panel are the median Gini and M20 coefficients of SBs in these three stellar mass bins. Gray dashed lines are the morphology classification from Lotz et al. (2008).
