Fig. 1

VISIR images of the P83 LLAGN in the filters PAH2 and NeIIref1. Each row shows one object sorted by right ascension. White corresponds to the mean background value ( ⟨ BG ⟩ ) and black color corresponds to ⟨ BG ⟩ + 10σBG with a linear scaling. The images of NGC 1667 were smoothed to increase the visibility of this low-S/N detection.
