Identification of the PAH features in IRAS 13258. On the top we plot the spectrum shortwards of 13 μm, together with a spline fit to represent the underlying continuum. The residual spectrum is given below, together with an example of the class B (orange) and class C (dark green) PAH features as described by Peeters et al. (2002) and van Diedenhoven et al. (2004).
