Channel maps of CO(3–2) emission in the centre of NGC 1433. Each of the 42 square boxes is 20′′  in size, while the primary beam is 18′′  in diameter . Channels are separated by 4.24 km s^-1. They are plotted from 978 (top left) to 1152 km s^-1 (bottom right, the panels are labelled in frequency). The synthesized beam is 056 × 042 (PA = 85°). The centre of the maps is the phase centre of the interferometric observations given in Table 1. The colour scale is linear, between 1 and 30 mJy/beam.
