A method to analyse velocity structure
  We present a new method of analysing and quantifying velocity structure in
star forming regions suitable for the rapidly increasing quantity and quality
of stellar position-velocity data. The method can be applied to data in any
number of dimensions, does not require the centre or characteristic size (e.g.
radius) of the region to be determined, and can be applied to regions with any
underlying density and velocity structure. We test the method on a variety of
example datasets and show it is robust with realistic observational
uncertainties and selection effects. This method identifies velocity
structures/scales in a region, and allows a direct comparison to be made
between regions.
