N₂H⁺(3−2) and 1.07 mm continuum data. The left panel and the contours in the three other panels always show the 1.07 mm continuum data starting from 3σ and continuing in 1σ steps with a 1σ value of 0.6 mJy beam^-1. The color scale in panels 2−4 present the N₂H⁺(3−2) integrated emission over the velocity regimes marked above each panel. The scaling ranges in panels 2 to 4 are [0, 0.15], [0, 0.25], and [0, 0.4] Jy km s^-1, respectively. The synthesized beam of the continuum and line data is shown each time in the bottom left. A scale bar can be found in the left panel.
