Top panel of each sub-figure: panchromatic SED of the respective galaxy. The black line is the best-fitting radiative transfer model, run at high-resolution. The green square points are the observed integrated luminosities measured for each galaxy (see Table A.1). The red, blue, and violet lines represent the SEDs for simulations with only one stellar component: old, young non-ionising, and young ionising stellar population, respectively. The interstellar dust component is still present in these simulations. Bottom panel of each sub-figure: difference in dex between the observations and the best-fitting model.
