Spectral fitting examples for galaxies from the ALHAMBRA survey using MUFFIT and the MIUSCAT SSP models. The galaxy photo-spectra and their errors are given in red, whereas the best-fitting models are given in blue. The top panel corresponds to a quiescent galaxy for which no emission lines are detected. The bottom panel illustrates the case of a star-forming galaxy for which MUFFIT detects three bands affected by emission lines, in yellow. The dashed black lines indicate the wavelengths for H β, H α, and [S ii]. Photometric redshifts are given in the insets in the figure.
