Monopoles at finite volume and temperature in SU(2) lattice gauge theory

We resolve a discrepancy between the SU(2) spatial string tension at finite temperature, and the value obtained by monopoles in the maximum Abelian gauge. Previous work had incorrectly omitted a term due to Dirac sheets. When this term is included, the monopole and full SU(2) determinations of the spatial string tension agree to within the statistical errors of the monopole calculation.
