¹²CO v = 0 J = 2-1 channel map of F01. The ordinate and co-ordinate axis give the offset of the right ascension and declination, respectively, with respect to the peak of the continuum emission (indicated by the cyan cross in the upper panels). The velocity is given in the upper left corner of each panel (in units of km s⁻¹). The cyan circle indicates the circular aperture of 075 (diameter) centred on the peak of the continuum emission that was used for extracting the CO(2-1) line profile. The ALMA beam is shown as a white ellipse in the bottom left corner of the bottom left panel. Upper plot: The contours (in orange) show the CO emission at [3, 5]×σ_rms (see Table A.1). The contours (in yellow) in the last panel show the continuum emission at [60, 90, and 99]% of the peak continuum emission.
