Fig. A.1.

Examples of combined line fitting with locked velocities for sources s1472, s1458, s1449, and s1521, as indicated in the top left corner of each frame. The best-fit values are also given in the frames in units of km s−1, km s−1, and K for the central velocity vLSR, the velocity dispersion σ, and the peak main-beam temperature Tmb, respectively.
