Same as Fig. 2 but for NGC 2273. Velocity contours (b and c panels) are from 1645 to 2015 km s⁻¹ in steps of 20 km s⁻¹. The continuum contours are −3σ (white dashed line), 3σ, 6σ and 9σ (solid lines) with σ = 46 μJy beam⁻¹. The residual velocity contours are from −50 to 50 km s⁻¹ in steps of 10 km s⁻¹. The velocity dispersion contours are in steps of 10 km s⁻¹ starting at 10 km s⁻¹.
