g − r and g − i colour (top panels) and stellar age and metallicity (bottom panels) profiles for IC 1199 as an example. The colour profiles are represented by means of purple circles (top panels). Blue circles represent light-weighted stellar age or metallicity; red squares symbolise mass-weighted stellar age or metallicity (bottom panels). The dot-dashed vertical line delimits the bulge-dominated region (R_lim,in), while the dashed vertical is located at the break radius (R_break).
