Velocity integrated intensity of the ¹²CO (3−2) (first column), ¹³CO (3−2) (second column), and C¹⁸O (3−2) (third column) for regions A (top) and B (bottom). The velocity range used for integration is − 20.1 < V_LSR < 8.2 km s⁻¹, − 15.0 < V_LSR < 3.1 km s⁻¹, and − 12.0 < V_LSR < −2.3 km s⁻¹ for ¹²CO (3−2), ¹³CO (3−2), and C¹⁸O (3−2), respectively. Contours represent the emission at 70 μm from Herschel and the cores (labels are slightly shifted from the true position of the cores) which were extracted in Figueira et al. (2017).
