Brightness temperature distribution of molecular and atomic gas along the line-of-sight to HESS J1741−302. The red dashed line indicates ¹²CO data from the Nanten survey, while the blue line shows HI data from the SGPS. The profiles are extracted from the circular region with a radius of 0.1° centered on the HESS J1741−302 best fit position. The abscissa shows the observed velocity of gas in km s⁻¹, while theordinate shows the brightness temperature (the left axis for HI and the right axis for ¹²CO) in K. Peaks in the ¹²CO brightness distribution are tagged with a number which indicates the corresponding interstellar cloud feature.
