Similar to Fig. 3 but for galaxies M and C. The top row shows the results for the CO J:3–2 line in both M and C together. The middle and bottom rows show the results for the CO J:7–6 line separately for M and C, respectively. In the right-most panels of the middle and bottom rows (the galaxy-integrated profiles of the CO J:7–6 lines in M and C, respectively) the CO J:7–6 line covers a velocity range of approximately ±300 km s⁻¹ and 500 km s⁻¹, respectively; for both galaxies the [C I] ³P₂→³P₁ line is also clearly visible at lower (∼1000 km s⁻¹ to the blue) velocities. We do not show the equivalent moment maps for the [C I] ³P₂→³P₁ line in M and C as they are significantly noisier.
