Distributions of the single-Sérsic, disc, and bulge half-light radii together with the bulge-to-total luminosity ratio of the PHIBSS2 z = 0.5 − 0.8 sample determined with galfit from their HST/ACS I-band images. In the middle and right panels, we only consider galaxies with B/T ≠ 1. The black dashed lines show the corresponding parent CANDELS/3D-HST H-band distributions at z = 0.5 − 0.8 with 10 <  log(M_⋆/M_⊙)< 11.8 and |log(δMS)| <  1 (van der Wel et al. 2012; Lang et al. 2014).
