Map of the continuum emission at 3 mm (Fuente et al. 2008) and line-integrated intensity maps of the 12.8 μm line of [NeII] (Achtermann & Lacy 1995), H(41)α, CO 2 → 1, CN 1 → 0, and N₂H⁺1 → 0 lines. The beam is drawn in the lower left corner of the panels, and positions E1, E2, W2, and W1 are indicated by filled polygons. The position of SN 41.9+58 is marked with a white cross. First contour is at 3 × σ level. Contour levels are 1.7 mJy/beam, 5 mJy/beam to 35 mJy/beam in steps of 5 mJy/beam (cont – 3 mm); 0.13 Jy/beam to 1.04 Jy/beam in steps of 0.13 Jy/beam ([NeII]); 4 to 28 in steps of 4 K × km s^-1 (H(41) α); 200, 400, 600, 800, 1200, 1600, 2000, 2400 K × km s^-1 (CO); 15.8 to 252.8 in steps of 15.8 K × km s^-1 (CN); 2.5, 5.0, 7.5, 10.0, 12.5 K × km s^-1 (N₂H⁺). Color scale is adjusted to the lowest and highest values in each panel.
