Velocity field maps of HerBS-54, HerBS-58, HerBS-89a, and HerBS-113. The maps were obtained for the emission lines of ¹²CO (4–3), [CI] (³P₁–³P₂), and ¹²CO (5–4) above thresholds of 30%, 20%, 10%, and 20% of the peak emission in the zeroth moment map for HerBS-54, HerBS-58, HerBS-89a, and HerBS-113, respectively. Contours are in units of 50 km s⁻¹ for HerBS-54 and HerBS-113, and of 100 km s⁻¹ for HerBS-58 and HerBS-89a. The synthesized beams are shown in the lower left corner of each panel.
