Examples of the ALMA ∼220 − 250 GHz continuum and CO(2–1) moment maps (from left to right: peak map, moment 0, 1, and 2) for a merger (20087−0308) and an interacting (10190+1322) starburst-dominated system and for a merger (01572+0009) and an interacting (12071−0444) AGN-dominated system. The blue crosses mark the position of the nuclei (see Table 1). The magenta ellipse shows the FWHM and position angle of the ALMA beam . The contours in the maps are: continuum map: [0.3, 0.4, 0.6, 0. 8, 0.9] of the maximum; peak map: 1.5 × σ (where σ is the rms) and [0.1, 0. 2, 0.4, 0.6, 0.8] of the maximum; moment 0: [3, 6, 25, 50, 75] × σ (where σ is the rms), moment 1: every 50 km s⁻¹ (every 25 km s⁻¹ if the maximum value < 100 km s⁻¹), moment 2: every 25 km s⁻¹ (every 15 km s⁻¹ if the maximum value < 150 km s⁻¹).
