Data used for the Fig. 3: distribution of $\pi_2(S^2)$ and $\pi_3(S^3)$ charges, for J=1, D=\sqrt{2}, and B=0.6.
The charge densities are calculated with Eq.(50).

Quantities:
	i	-> lattice site (x=i%L, y=(i//L)%L, z=(i//L^2)%L)
	S1	-> first component of spin in lattice site i
	S2	-> second component of spin in lattice site i
	S3	-> third component of spin in lattice site i
	S4	-> fourth component of spin in lattice site i

Format:
i	S1	S2	S3	S4
