Comparison between the STECKMAP and STARLIGHT (using spectral templates mimicking constant SFR) best models. Top panel: the STECKMAP best model is plotted in red. The STARLIGHT best model is plotted in blue. Bottom panel: residuals of both best models (STECKMAP – STARLIGHT). The shaded regions of the spectrum are the masked regions (not considered in the fits). Vertical, dashed red lines are located at the wavelengths of the main stellar absorption features. The residuals are in units of 10^-15 erg^-1 cm^-2 Å^-1.
