Spectra of the deconvolved point-source emission (black) and the non-deconvolved data (grey). We note that since the flux density in the line channels are sums of the line and continuum flux densities, these will not be properly cleaned (line strengths are under-estimated in these spectra owing to the more extended continuum). The deconvolved spectra shown here are used to check for consistency with the continuum deconvolution (see Sect. 3.2), but not for extracting line fluxes (see Sect. 3.3 for a description of the method used for the line flux deconvolution).
