Our SOFIA spectrum of IRAS 05341+0852 (blue) is compared to other spectra from the literature, including another SOFIA spectrum (orange; Materese et al. 2017), a Spitzer/IRS spectrum (AORkey: 4896512, PI: Dale Cruikshank), and an ISO/SWS spectrum (Matsuura et al. 2014). The dashed lines represent the applied continua for the corresponding spectra (in the same colour). The lower panel displays the residual after subtracting a spline continuum. See Sect. 3.3 for details.
