Colour maps of the integrated intensity of the J = 2 → 1, J = 3 →2, J = 6 →5, and J = 7 → 6 transitions of ¹²CO, the J = 2 → 1, J = 4 →3, and J = 6 → 5 transitions of ¹³CO, the J = 2 → 1 line of C¹⁸O and [C I] 1 → 0 toward Her 36. This corresponds to the central position (Δα = 0, Δ δ = 0) at RA(J2000) = 18^h03^m40.3^s and Dec(J2000) = −24°22′43′′, denoted with an asterisk. The contour levels of ¹²C¹⁸O and [C I] are 3 × rms in steps of 2 × rms, while those of other molecules are from 10% (>3 × rms, given in Table 1) to 100% in steps of 10% of the corresponding peak emission given in Table 1. All maps are plotted using original beam sizes shown in the lower left of each map.
