We see here two molecular lines from the $^{12}$CO($J=2\to 1$) rotation transition. I think the vertical axis is magnitude (brightness) and the horizontal axis for both is radial velocity, though I’m not sure the units. Perhaps the usual km/s.
I’m back at it (finally). I’m still looking at MBM 12; an abstract for my poster will be up sooner or later. Especially since the abstract deadline is in just a few weeks. I also have data from other molecules containing carbon, as well as atomic carbon. I want to see if anything traces the dark gas well, since $^{12}$CO likely won’t do the job well in this region. I just randomly managed to choose CO when plotting spectra to get a handle on what I was seeing.
