Notes. Cloudlet grouping is adopted from Surcis et al. (2015). ΔRA and ΔDec correspond to the relative coordinates to the maser spot at ![Mathematical equation: $\[\mathrm{RA}\mathrm{=}18^{\mathrm{h}} 54^{\mathrm{m}} 14^{\mathrm{s}}_\cdot22920, ~\mathrm{Dec}\mathrm{=}\mathrm{+}04^{\circ} 41^{\prime} 41^{\prime \prime}_\cdot0501\]$](/articles/aa/full_html/2026/04/aa57926-25/aa57926-25-eq5.png)
(J2000). Vp is the peak velocity, Vfit is the fitted velocity, FWHM is the full–width at half maximum of the Gaussian profile, Sp is the peak brightness, Sfit is the fitted brightness, Lproj is the projected linear size of cloudlet, Vgrad is the velocity gradient and PA is the position angle of the major axis of cloudlet. Entries in italic are uncertain.
