"In this example, we are fitting the complex continuum around Lyman-alpha in the spectrum of an active galaxy (NGC 5548). This involves a powerlaw, extinction, emission lines of various widths and absorption lines. Only certain regions of the spectrum (away from strong absorption lines) are fit. The model has some fixed and some free parameters, as well as parameters that are linked together. We are using the Astropy compound-model machinery to add fit all the components simultaneously. \n",
