Query: Effect of Sub-Structure in Clusters on the Local Weak-Shear Field   Weak shear maps of the outer regions of clusters have been successfully used
to map the distribution of mass at large radii. The effects of substructure in
clusters on such reconstructions of the total mass have not been systematically
studied. We propose a new method to study the effect of perturbers (bright
cluster galaxies or sub-groups within the cluster) on the weak shear field. We
present some analytic results below.
