  We demonstrate that 4-body real space Jastrow factors are, with the right
type of Jastrow basis function, capable of performing successful wave function
stenciling to remove unwanted ionic terms from an overabundant fermionic
reference without unduly modifying the remaining components. In addition to
greatly improving size consistency (restoring it exactly in the case of a
geminal power), real-space wave function stenciling is, unlike its Hilbert
space predecessors, immediately compatible with diffusion Monte Carlo, allowing
it to be used in the pursuit of compact, strongly correlated trial functions
with reliable nodal surfaces. We demonstrate the efficacy of this approach in
the context of a double bond dissociation by using it to extract a
qualitatively correct nodal surface despite being paired with a restricted
Slater determinant, that, due to ionic term errors, produces a ground state
with a qualitatively incorrect nodal surface when used in the absence of the
Jastrow.
