Notes. Structural parameters and the flux contribution of each component relative to the total flux for the single-component model (‘single’) and for each component of the two-component model (‘inner’ and ‘outer’) at the r-band central wavelength 6166 Å. The conversion of R_e from arcseconds to kiloparsecs was computed with R_e [kpc] = 4.848 × 10⁻⁶ × dA(z) [kpc] × R_e [arcsec], where dA is the redshift-dependent angular diameter distance in kiloparsecs to each galaxy.
