Scientific paper

Cluster mass substructure is an important test of the hierarchical model
of CDM. We use weak gravitational lensing shear measurements, combined
with variable aperture filter methods and PSF correction, to extract
information about mass subclumping in HST observations of clusters of
galaxies. This work is funded by NASA Rhode Island Space Grant.
