  The probability density of low-lying eigenvectors of the hermitian
Wilson-Dirac operator is examined. Comparisons in position and size between
eigenvectors, topological charge and action density are made. We do this for
standard Monte-Carlo generated SU(3) background fields and for single instanton
background fields. Both hot and cooled SU(3) background fields are considered.
An instanton model is fitted to eigenmodes and topological charge density and
the sizes and positions of these are compared.
