ALMA moment maps. ALMA first three moment maps obtained from the 2017.1.01439.S data-set selecting the baselines in order to separate the CO(2-1) emission over extended (top panels) and compact angular scales (bottom panels). From left to right: Integrated flux (moment-0), mean velocity (moment-1), and velocity dispersion (moment-2). The grey ellipses in lower-left corner show the synthesised beam size (i.e. the angular resolution): 2.18 × 2.03 arcsec2 at PA = -82 deg and 0.52 × 0.45 arcsec2 at PA = 81 deg (top and bottom panels respectively).
