Notes. PAslit indicates the position angle of the slit measured from the north counterclock rotation. NGC 7172 was observed on several nights, but the majority of the observations were taken with a slit PA = 90 deg. “PAH det” indicates whether the 11.3 μm PAH feature was detected in the nuclear spectrum. The distance from the AGN rAGN for the PAH detection (or nondetection) is computed as half the slit width. The last column provides the reference of the published mid-IR spectrum for each galaxy.
