Hence, the ecCodes values array contains the coefficients in the order Re(X(0,0)), Im(X(0,0)), Re(X(1,0,1)), Im(X(1,0,1), Re(X(2,0,2)), Im(X(2,0,2)), … , Re(X(T,0,T)), Im(X(T,0,T)), Re(X(1,1)), Im(X(1,1)), Re(X(2,1,2)), Im(X(2,1.2)), … , Re(X(T,1,T)), Im(X(T,1,T)), ... ,Re(X(T,T-1,T)), Im(X(T,T-1,T)), Re(X(T,T)), Im(X(T,T)).

Only the coefficients for m ≥ 0 are stored. The coefficients for m < 0 are obtained from the complex conjugates of the corresponding coefficient with m > 0 : as X(n,-m)= X*(n,m) / (-1)m |
The spherical harmonic (n, m) wave number space is shown in the figure.
