Integrated ¹²CO column density maps of the region around HESS J1741−302 for each cloud as labeled in Fig. 3. Velocity integration intervals used for producing the corresponding column density map is given for each cloud. The dashed blue circles show the HESS J1741−302 region which is marked with a dashed black circle in Fig. 1, while the white dashed line indicates the orientation of the Galactic plane. The color scale is in the units of 10²⁰ cm⁻².
