Smoothed naturally weighted SMA 1.3 mm continuum (upper left) in NGC 1614. The noise level is 0.71 mJy/beam. Contours start at 1.5σ in steps of 1.1σ. Integrated intensity map (upper right), velocity field (bottom left), and velocity dispersion (bottom right) of the CO (2−1) emission in NGC 1614. The noise level is 6.16 mJy/beam. Contours for the integrated intensity map start at 4σ in steps of 4σ, contours for the velocity field and velocity dispersion start at 5σ. The velocity range plotted in the velocity field is between ~4520 km s^-1 and ~4985 km s^-1. The beam sizes are indicated in the lower left corner of each plot and are listed in Sect. 2.
