By connecting all vectors using a [[Delaunay triangulation]] criterion it is possible to characterize gradient assymetriesasymmetries computing the so-called ''gradient asymmetry coefficient'', that has been defined as:

<math>G_A=\frac{N_C-N_V}{N_V}</math>,

where <math>N_{V} > 0</math> is the total number of asymmetric vectors, <math>N_{C}</math> is the number of Delaunay connections among them and the property <math>N_{C} > N_{V}</math>
