Technical Note
The filters were chosen to include prominent aromatic infrared bands due to emission by Polycyclic Aromatic Hydrocarbons (PAHs). The FLITECAM filter includes emission due to the C-H stretch mode at 3.3 µm and the FORCAST filter includes emission from the solo out-of-plane bending mode at 11.2 µm.
