Example of spectral fittings for one galaxy (HATLASJ083832). Top left: CIGALE SED fit, where points represent the broadband magnitudes from the GAMA survey and the red, orange, blue, and green lines represent the dust spectra, stellar spectra, stellar spectra attenuated by the dust, and emission-line continuum spectra, respectively. Blue points represent the UV and optical bands, and the red points represent the IR bands. Top right: STARLIGHT stellar continuum fit, with the black and red lines representing observed and modeled spectra, respectively. Bottom left: single-Gaussian fit of the Hα+[N II] emission lines, where the points and the black line represent the observed spectrum, and the red line represents the modeled lines. A residual spectrum is shown in the bottom part of the panel. Bottom right: same as the previous panel, but showing the double-Gaussian fit, where both components are represented by blue lines. The Gaussian and STARLIGHT fits are from the same spaxel, located in the central region of the galaxy.
