In this section, we briefly present the theory of ADCIGs
Biondi and Tisserant (2004); Rickett and Sava (2002); Sava and Fomel (2003) and the
derivation of the mathematical expression of RMO in anisotropic
ADCIGs as a function of errors in anisotropic velocity parameters
Biondi (2005a,b); Jousselin and Biondi (2006).
