Histogram of available galaxy velocities, including our observations, in the range 8000 ≤ v ≤ 35 000 km s⁻¹ (left), and between 8000 ≤ v ≤ 16 500 km s⁻¹ (right) with a step size of 500 km s⁻¹ (blue). In the right panel, green and brown colours represent data sets from Andreuzzi et al. (1998) and the region around CID36 region, respectively. A Gaussian fit to the data, shown as a blue solid line, includes all the available data in the right panel.
