Spectral energy distribution fits of the galaxies from Herschel sample. Observed spectra in the optical and MIR ranges are shown by black and magenta lines. Photometric data are shown from GALEX (blue filled circles), SDSS (open magenta circles), 2MASS (black open circles), WISE (green symbols), Spitzer (black filled circles), Herschel (red filled circles), and submm and radio (open magenta rhombs). Blue, green and red spectra at λ<15 μm are fitted SEDs for ionised gas, stellar and total emission, which are produced from the optical spectra. Fits of dust emission at λ> 5 μm are shown by red, green, and blue dotted lines for different components and by black solid line for total emission. Blue solid line at λ> 100 μm is free-free emission extrapolated from the extinction- and aperture-corrected Hβ flux. Blue dashed line indicates the wavelength at which dust flux is equal to extrapolated free-free emission.
