Final best-fit model for the 2012–13 stacked spectrum of NGC 1365 with 4.5 × solar nitrogen abundance, two collisional emission models representing the starburst ionised gas and three photoionised emission models representing the AGN ionised gas. The data are shown in black, the total model in red and the absorbed powerlaw component in pink. The collisional emission components are combined and shown in green. The photoionised emission phases are combined and shown in blue. The data are binned by two for display purposes. For details see text and Table 4.
