Dereddened spectrum of the full MUSE field of NGC 4361, with the area of the central star subtracted, is shown with the fit of the H⁺, He⁺ and He⁺⁺ nebular continua (in blue, yellow and red, respectively). The sum of the three sets of continua is shown in green. The fit to the spectrum is shown in magenta and includes a scattered light contribution modelled as a third-order polynomial continuum to match the sum of the nebular continua to the measured nebular spectrum. See text for further details and Table 5 (Columns 5 and 6) for the fitted jump temperatures (H I Paschen jump and He II n=5 jump).
