Moment-0 maps of ¹²CO (3–2) (left) and ¹³CO (3–2) (right) lines toward the G305 GMC complex. In both maps, the emission has been integrated over a velocity range from − 70 to + 10 km s⁻¹. Pixels with no emission >5σ for at least three consecutive velocity channels have been excluded (seen in white). Overlaid on top as green stars are the positionof stars as reported in Borissova et al. (2019). The red circles show the positions of the Danks 1 and 2 clusters, and the red star is WR48a. The numbered regions are discussed in the text.
