Examples of multicomponent spectral fitting in the 4100 − 7000 Å rest-frame range for the +179 days spectrum (solid gray line). The underlying continuum emission and all emission-line components are plotted with different colors, as indicated in the legend. For details on the assumed emission-line components see text. The final model (solid red line) which is the sum of all components is also shown, whereas the residual spectrum, is plotted below.
