Channel map of the ¹²CO(3−2) observationscarried out with APEX. The 10′ × 10′ field is shown in its entirety. Each panel represent the emission integrated over an interval of velocity along the line of sight. Velocities are indicated on the top left corner of each panel. Velocity channels represented in this figure are between v = − 24 km s⁻¹ and v = +12 km s⁻¹, covering all the spectral features detected toward the extended G region.
