We demonstrate that 4-body real space Jastrow factors are, with the righttype of Jastrow basis function, capable of performing successful wave functionstenciling to remove unwanted ionic terms from an overabundant fermionicreference without unduly modifying the remaining components. In addition togreatly improving size consistency (restoring it exactly in the case of ageminal power), real-space wave function stenciling is, unlike its Hilbertspace predecessors, immediately compatible with diffusion Monte Carlo, allowingit to be used in the pursuit of compact, strongly correlated trial functionswith reliable nodal surfaces. We demonstrate the efficacy of this approach inthe context of a double bond dissociation by using it to extract aqualitatively correct nodal surface despite being paired with a restrictedSlater determinant, that, due to ionic term errors, produces a ground statewith a qualitatively incorrect nodal surface when used in the absence of theJastrow.
