FVLRD[p,mu,n,nb]
denotes the perpendicular component in the lightcone decomposition of the Lorentz vector along the vectors n
and nb
in dimensions. It corresponds to .
If one omits n
and nb
, the program will use default vectors specified via $FCDefaultLightconeVectorN
and $FCDefaultLightconeVectorNB
.
