Fig. 5
Number distribution of vlsr difference between H II region and HMSC 
in the −30 to 30 km s−1
range. The gray lines are the fitted Gaussian and its center. The pink histogram highlights the distribution for S-type HMSCs (see Sect. 4.4). The red and blue dashed lines represent 1 and 2σ
of Gaussian, respectively. The median value of 
overlaps with Gaussian center in the figure.
