Observed NIKA2 maps of NGC 2146 (top) and NGC 2976 (bottom) at 1.15 mm (left) and 2 mm (right). The color bars show the flux density in units of mJy/beam. The circle in the bottom left corner of each panel indicates the angular resolution (beam widths) which is 12″ and 18″ at 1.15 mm and 2 mm, respectively. The contours show the MIPS 24 μm emission at levels 9, 54, and 324 Jy/pixel in the top panels and 0.8, 2.4, and 7.2 Jy/pixel in the bottom panels. The FoV is 4′×4′ and 5′×5′ for NGC 2146 and NGC 2976, respectively.
