Example of full spectral fitting performed with pPXF for three galaxies at redshift z = 0.7. The rest-frame noiseless spectra (black solid lines) are plotted with the best-fitting model (orange lines). Each emission line is modelled with one kinematic component. The best-fitting stellar spectrum alone and the gas emissions alone are shown with red and magenta solid lines, respectively. The residuals (green diamonds; arbitrarily offset) are calculated by subtracting the model from the observed spectrum.
