Functions  
Real  norm (const BoxLayoutData< FArrayBox > &A, const Interval &interval, const int &p=2) 

not actually Lp norms, since it doesn't take into account the dx of the system. A user can take that into account or not. For p != 0, returns pth root of sum of pth powers over all points in all fabs and all components in the interval: ( sum [ A[i][pt,var]^p : FArrayBox A[i], point pt in A[i].box(), var in interval ] )^(1/p) To turn into an Lp norm, one needs to multiply this by dx^(SpaceDim/p). For p == 0, returns global max over all points in all fabs and all components in the interval: max [ A[i][pt,var] : FArrayBox A[i], point pt in A[i].box(), var in interval ] Some people don't like that this norm is not normalized based on number of points in A. Normalization is your problem.
