DISCMINER results and comparison to CN data. First row: selection of channel maps from the CN datacube. Velocities are relative to the systemic velocity, and the spectral resolution of each channel is 0.1 km s^–1. Middle row: channel maps from the best-fit DISCMINER model, at the same spatial resolution and intensity scale as the observations. Bottom row: residual (observations minus model) emission. Contours indicate 5σ positive (red) and negative (purple) residuals, where σ is the data rms (1 mJy beam^–1).
