Resulting spectra and respective fits for LTG IC 2604 – panel a displays the spectrum of the bulge (red), disk (dark-blue) and scaled disk (light-blue) according to the exponential disk distribution (additionally it can be seen the overplotted SDSS g-band transmission curve in soft gray). Panel b: displays the residuals (in %) between the modeled and observed spectrum for the bulge (red) and disk (dark-blue) with the black horizontal line corresponding in either case to a percentage deviation of 0%. The vertical arrow corresponds to a percentage deviation of 50%. At panel c it is shown in black the resulting net-bulge spectra after subtraction of the three different models for the disk and overplotted are the respective stellar fits. The residuals, that is the difference between obtained net-bulge SED and respective stellar fits divided by the observed, are shown in panel d. As in panel b we shift the residuals by an arbitrary amount (in this case, by 10%; cf. vertical arrow) for the sake of better visibility. Labels on the r.h.s. of the panels list the bulge and disk stellar mass log(ℳ_⋆), and mass-weighted mean stellar age ⟨t_⋆, B⟩_ℳ and metallicity ⟨Z_⋆, B⟩_ℳ prior to subtraction, the scaling factors for each of the disk configuration and ⟨t_⋆, B⟩_ℳ and ⟨Z_⋆, B⟩_ℳ for each of the fits (where dD, fD and eD corresponds to centrally decreasing, flat and exponential disk, respectively), as obtained with STARLIGHT and Z4 stellar library.
