Fig. 6. Top panel: CVF spectrum towards  Ori A (solid line). The ordinates give fluxes in Jy per pixel. A Lorentz fit to the AIBs is shown as the dotted line. Middle panel: result of the subtraction of the AIBs from the CVF spectrum. The fit to the continuum is shown by the dotted line. Bottom panel: Residual from the middle figure, i.e. the suspected amorphous silicate emission profile; notice the narrower bump near 9.6 µm .
