Selection of 30 m spectra towards the offsets (+240′′,0), (120′′,0) and (0,0) in the TMC 1-CP cut. In order to investigate the velocity structure we have fitted the observed line profiles with 5 Gaussians with a fixed linewidth of 0.5 km s−1, each centered at the velocities 5.0 (green), 5.5 (dark blue), 6.0 (light blue), 6.5 (yellow) and 7.0 km s−1 (fuchsia).
