Left: 0th moment of the ¹²CO(2–1) observationscarried out with the IRAM 30 m over the extended G region. This map corresponds to the signal integrated in the velocity interval [−40; +30] km s⁻¹. The color scale used to represent data is logarithmic to enhance the dynamic range and emphasize the fainter molecular cloudlet. Right: composite image of our field of observations in the extended G region, using an IRAM 30 m data cube as well as Spitzer-MIPS data; ¹²CO(2–1) ([−40, +30] km s⁻¹ as in the left panel) is coded in red, MIPS-24 μm in blue, and ¹³CO(1–0) [−4.0, −2.5] km s⁻¹, corresponding to the emission spatially and kinematically associated with the ambient cloud described by Lee et al. (2012) in green. Color scale levels are based on the minimum and maximum value of each map.
