Caption: Figure 4.

Observed molecular line spectra of the clumpy cloud in I19368. The histogram shows the HCO+(3−2) line (upper panel) and the H13CO+(1−0) line (lower panel). The Gaussian fitting for the H13CO+(1−0) line gives the systematic velocity (the vertical blue dashed line) of this source. This figure was adapted from H. Yoo et al. (2018).
